An unnamed young man lives an ethereal existence that lacks transitions between everyday events and eventually progresses toward an existential crisis. He observes quietly but later participates actively in philosophical discussions involving other characters—ranging from quirky scholars and artists to everyday restaurant-goers and friends—about such issues as metaphysics, free will, social philosophy, and the meaning of life. Other scenes do not include the protagonist but rather focus on an isolated person, a group of people, or a couple engaging in such topics from a disembodied perspective. Along the way, the film also touches upon existentialism, situationist politics, posthumanity, the film theory of André Bazin, and lucid dreaming, and references various intellectual and literary figures by name. Gradually, the protagonist realizes that he is living out a perpetual dream, broken up only by occasional false awakenings. So far, he is mostly a passive onlooker, though this changes during a chat with a passing woman who suddenly approaches him. After she greets him and shares her creative ideas with him, he reminds himself that she is a figment of his own dreaming imagination. Afterward, he starts to converse more openly with other dream characters, but begins to despair about being trapped in a dream. The protagonist's final talk is with a character (played by Linklater) whom he briefly encountered earlier in the film. This conversation reveals this other character's view that reality may be only a single instant that a person interprets falsely as time (and, thus, life); that living is simply the person's constant negation of God's invitation to become one with the universe; that dreams offer a glimpse into the infinite nature of reality; and that to be free from the illusion called life, one need only accept God's invitation. The protagonist is last seen walking into a driveway, when he suddenly begins to levitate, paralleling a scene at the start of the film of a floating boy in the same driveway. The protagonist uncertainly reaches for a car door handle but is too swiftly lifted above the vehicle and over the trees. He rises into the endless blue expanse of the sky until he disappears from view.

On the Polynesian island of Motunui, the inhabitants worship the goddess of nature, Te Fiti; a living island who, long ago, brought life to the ocean using a pounamu stone as her heart and the source of her power. One day, Maui, the shape-shifting demigod of the wind and sea and master of wayfinding, stole Te Fiti's heart to give humanity the power of creation. This caused Te Fiti to disintegrate, and Maui was attacked by Te Kā, a volcanic demon. Maui lost both the heart and his magic fish hook to the depths of the sea. A thousand years later, the ocean chooses Moana, the daughter of Motunui's chief Tui, to return the heart to Te Fiti. Tui and Sina, Moana's parents, try to keep her away from the ocean to prepare her to become the island's chief. Sixteen years later, blight strikes the island, killing vegetation and shrinking the fish catch. Moana suggests going beyond the island's reef with her pet pig, Pua, to find more fish and discover what is happening, but Tui forbids it. Moana tries conquering the reef, but is overpowered by the tides and shipwrecked. That afternoon, Moana's grandmother Tala shows her a secret cavern of ships and reveals Motunui's people were voyagers until Maui stole Te Fiti's heart; the ocean was no longer safe without it. Tala explains Te Kā's darkness is destroying the island, but can be cured if Moana finds Maui and has him restore the heart of Te Fiti. Having been given the heart by the ocean, Tala gives it to Moana. Tala later becomes gravely ill and tells Moana to find Maui. Moana sets sail on a camakau from the cavern along with her dimwitted pet rooster, Heihei, who stowed away on it. They are caught in a typhoon and shipwrecked on an island, where she finds Maui, who boasts about his achievements. She demands Maui return the heart, but he refuses and traps her in a cave before leaving on her boat. She escapes and confronts Maui, who reluctantly lets her on the camakau. They are attacked by Kakamora, coconut pirates who seek the heart, but Moana and Maui outwit them. Moana realizes Maui is no longer a hero since he stole the heart and cursed the world, and convinces him to redeem himself by returning the heart. However, Maui first needs to retrieve his fishhook in Lalotai, the Realm of Monsters, from Tamatoa, a giant coconut crab. While Moana distracts Tamatoa, Maui retrieves his hook, only to find himself unable to control his shape-shifting. He is overpowered by Tamatoa, but Moana's quick thinking allows them to escape with the hook. Maui reveals his first tattoo was earned when his human parents abandoned him as an infant, and the gods, taking pity on him, granted him his powers. After reassurance from Moana, Maui teaches her the art of way-finding, regaining control of his powers, and the two grow closer. They arrive at Te Fiti's island, only to be attacked by Te Kā. Moana refuses to turn back, resulting in Maui's hook being badly damaged. Unwilling to lose his hook again, Maui abandons Moana, who loses hope and tearfully asks the ocean to find someone else to restore the heart. The ocean obliges and takes the heart, but Tala's spirit appears, inspiring Moana to find her true calling. Moana retrieves the heart and sails back to confront Te Kā. Maui returns, having had a change of heart, and buys Moana time to reach Te Fiti by fighting Te Kā, destroying his hook in the process. Upon being unable to find Te Fiti, Moana realizes Te Kā is Te Fiti, but corrupted without her heart. The ocean clears a path for Moana, allowing her to return the heart to Te Fiti, who heals the ocean and islands of blight. Maui apologizes to Te Fiti, who fixes his hook as well as Moana's boat before falling into a deep sleep and becoming an island. Moana bids farewell to Maui and Te Fiti, returning home and reuniting with her parents. After placing a shell on top of the stack of stones placed by all previous chiefs, Moana takes up her role as chieftess and wayfinder, leading her people as they resume voyaging, accompanied by Maui.

In the Valley of Peace province of Ancient China, the red panda Master Shifu learns from his mentor, the tortoise Master Oogway, that the snow leopard Tai Lung will escape from imprisonment and attempt to acquire the Dragon Scroll, an artifact said to grant limitless power. In response, Shifu sends warning to the guards at Tai Lung's prison to strengthen security and announces a tournament to dub one of his five students, collectively known as the "Furious Five", Tigress, Monkey, Crane, Viper, and Mantis, as the "Dragon Warrior", the prophesied hero worthy of reading the scroll. The announcement reaches Po, a giant panda and kung fu enthusiast who dreams of becoming a kung fu master himself, despite wishes from his goose father Mr. Ping for him to run their noodle restaurant and learn the secret ingredient of his "secret ingredient soup". Eager to see the Five, Po attempts to enter the tournament arena after arriving late and is eventually successful, but unintentionally lands in front of them during the awarding ceremony, causing Oogway to unexpectedly declare him as the Dragon Warrior. Shifu believes Oogway's choice to be an accident, leading him and the Five to dismiss and deride Po after a rough first day of training, leaving Po dejected and considering quitting. However, Oogway encourages him to persevere, and Po gradually befriends the Five with his resilience and humor. Tigress reveals to Po that Tai Lung was once Shifu's student, having raised him as an infant, and how Tai Lung's betrayal and subsequent rampage was a result of Oogway rejecting him as the Dragon Warrior after sensing malice within him. Tai Lung manages to break out of prison and begins his journey back to the Valley; when Shifu learns this and tells Oogway about it, Oogway makes him promise to believe in Po and names Shifu his successor before ascending to the Spirit Realm. Shifu then informs Po and the Five about Tai Lung's escape, stating Po is the only one who can stop him. Terrified, Po attempts to leave but is confronted by Shifu, who confesses that he does not know how he can turn him into the Dragon Warrior. Meanwhile, the Five depart to attempt to stop Tai Lung themselves, but are unsuccessful when he uses his paralysing nerve-strike technique on them. Shifu learns that Po can reach his full potential for physical feats when motivated by food, and so trains him in a unique kung fu style. When the wounded Five return, Shifu decides that Po is ready to read the Dragon Scroll, but upon opening it, Po discovers that it is blank. Thinking the scroll is powerless, Shifu sends Po and the Five to evacuate the Valley while he faces Tai Lung alone. A saddened Po reunites with Mr. Ping, who, in an attempt to lift his spirits up, reveals that the secret ingredient soup does not actually have a secret ingredient, stating that belief is what makes things special. Realizing that this is the Dragon Scroll's message, Po rushes back to help Shifu. Shifu battles Tai Lung and is brutally defeated, then Po arrives with the scroll and engages Tai Lung in combat. Tai Lung manages to obtain the scroll, but is similarly mystified by its contents. Enraged, he nerve-strikes Po, who is unaffected due to his body fat. Remembering his earlier training with Shifu, Po overpowers Tai Lung and vanquishes him with the "Wuxi Finger Hold" technique, which he had taught himself, and is hailed as a hero by the Valley.

Fujimoto, a misanthropic wizard who was once a human, lives underwater with his daughter Brunhilde and her numerous smaller sisters, who are goldfish-like creatures with human faces. While she and her siblings are on an outing with their father in his four-flippered submarine, Brunhilde sneaks off and floats away on the back of a jellyfish. After an encounter with a fishing trawler, she becomes trapped in a glass jar and drifts to the shore of a small fishing town where she is rescued by a five-year-old boy named Sōsuke. While shattering the jar with a rock, Sōsuke cuts his finger. Brunhilde licks his blood, healing the wound almost instantly. Sōsuke names her Ponyo and promises to protect her. Meanwhile, a distraught Fujimoto searches frantically for his lost daughter whom he believes to have been kidnapped. He calls his wave spirits to recover her, leaving Sōsuke heartbroken and confused by what happened. Ponyo refuses to let her father call her by her birth name, declaring her desire to be a human named Ponyo. She magically begins changing into a human, a power granted to her by Sōsuke's human blood that she licked. Fujimoto forces her back into her true form and leaves to summon Ponyo's mother, Gran Mamare. Meanwhile, Ponyo, with the help of her sisters, breaks away from her father and inadvertently uses his magic to make herself human. The huge amount of magic that she releases into the ocean causes an imbalance in nature, resulting in a tsunami. Ponyo goes back to Sōsuke, who is amazed and overjoyed to see her. His mother, Lisa, allows her to stay at their house. Lisa leaves after the tsunami subsides to check up on the residents of the nursing home where she works, promising Sōsuke that she will return home as soon as possible. Gran Mamare arrives at Fujimoto's submarine. Sōsuke's father, Kōichi, sees her traveling and recognizes her as the Goddess of Mercy. Fujimoto notices the moon appears to be falling out of its orbit and satellites are falling like shooting stars, symptoms of the dangerous imbalance of nature that now exists. Gran Mamare reassures him, and declares that if Sōsuke can pass a test, Ponyo can live as a human and the balance of nature will be restored. Fujimoto, still worried, reminds her that if Sōsuke fails the test, Ponyo will turn into sea foam. The next day, Sōsuke and Ponyo find that most of the land around the house has been covered by the ocean. Since it is impossible for Lisa to come home, the two decide to find her. With Ponyo's magic, they make Sōsuke's pop-pop boat bigger to traverse the waters, seeing marine life from the Late Devonian period and more people on boats. When they reach the forest, however, Ponyo tires and falls asleep, and the boat slowly reverts to its original size. Sōsuke drags Ponyo to the shore, where he finds Lisa's abandoned car. As they continue walking, Ponyo mysteriously reverts to her fish form. Meanwhile, Gran Mamare grants Lisa and the residents of the nursing home the temporary ability to breathe in water. Ponyo and Sōsuke encounter Fujimoto, who warns the boy about the imbalance of nature and begs him to return Ponyo to him. Despite their attempt to escape, Fujimoto captures them and transports them to the protected nursing home. Sōsuke reunites with Lisa and meets Gran Mamare, with whom Lisa has just had a long private conversation. Gran Mamare asks him if he can love Ponyo whether she is a fish or human; Sōsuke confirms that he does. She then informs her daughter that she must relinquish her magical powers if she decides to permanently transform into a human. Ponyo agrees, and she is encased in a bubble given to Sōsuke, who is instructed to kiss it to complete Ponyo's transformation, as the balance of nature is restored. The previously stranded ships head back to port. Fujimoto respects his daughter's choice, having decided he can trust Sōsuke. Ponyo then joyfully jumps high in the air and kisses Sōsuke, completing her transformation into a human.

In 2200, Aline Ruby, a private detective, and Carlos Rivera, an android replica of her partner who died five years earlier, are sent to Earth to capture Roberta Williams, a robot-hacking criminal. Back on Mars, Roberta's arrest warrant has disappeared and she is released. A new investigation is entrusted to the duo: to track down Jun Chow, a cybernetics student known for illegally jailbreaking androids who, like her roommate, has gone missing. Aline and Carlos venture to the depths of Noctis, the main terrestrial establishment of Mars created thanks to the progress of robotics, and where humans and various forms of androids seem to coexist in harmony. The city turns out to hide secrets such as trafficking and clandestine computer labs. Meanwhile, activists try to free the robots from the security constraints that bind them to humans. Ultimately, the robots are successfully emancipated and revolt, but peacefully, by uploading their consciousnesses to computers aboard spaceships and thus escaping to space. Carlos, grief-stricken by the loss of his partner and realizing that he is a dead consciousness embodied in a machine who has been "trying to hold onto a life that's moved on without him", decides to go with the robots.

Mrs. Brisby, a widowed field mouse, lives in a cinder block with her children on a farm owned by the Fitzgibbons family. She intends to move her family out of the field as plowing time approaches, but her son Timothy has fallen ill, making it impossible for him to travel. Brisby visits Mr. Ages, a friend of her late husband Jonathan, who diagnoses the illness as pneumonia, provides her with medicine, and warns that Timothy must stay inside for at least three weeks to recover. On her way home, Brisby befriends Jeremy, a clumsy but amiable crow, shortly before they narrowly escape the Fitzgibbons' cat, Dragon. The next morning, she discovers that the plowing has begun early. Although her neighbor, Auntie Shrew, helps disable the tractor used for the task, Brisby realizes she needs a better plan. Jeremy then takes her to meet the Great Owl, who at first rejects her, but upon learning she is Jonathan Brisby’s widow, tells her to visit a colony of rats living beneath a rose bush on the farm and seek out Nicodemus, their wise and mystical leader. Brisby enters the rose bush and encounters an aggressive guard rat named Brutus, who chases her away. She is led back in by Ages and is amazed to see the rats' use of electricity and other technology. Brisby meets Justin, the friendly captain of the guard; Jenner, a ruthless and power-hungry member opposed to Nicodemus; and finally Nicodemus himself. From Nicodemus, she learns that many years ago the rats, along with her husband and Ages, were part of a series of experiments at the National Institute of Mental Health (NIMH for short). The experiments gave them human-like intelligence, enabling them to escape, as well as extending their lifespans. They are unable to live as typical rats would, however, and need human technology to survive, which they can get only by stealing, placing them at great risk of discovery. To avoid being at the mercy of humankind again, the rats have collectively decided to leave the farm and live independently in an area they refer to as Thorn Valley. Nicodemus then gives Brisby a magical amulet that will activate when the wearer is courageous. Meanwhile, Jenner, who wishes for the rats to remain in the rose bush, plots to eliminate Nicodemus. Out of respect for Jonathan, the rats agree to help her move her home. First, they need to drug Dragon so it can be done without interference. Only Brisby can do this, as the rats cannot fit through the hole leading into the house; Jonathan was killed by Dragon in a previous attempt, while Ages broke his leg in another. That night, she puts the drug into Dragon's dish, but the Fitzgibbons' son catches her. While trapped in a birdcage, she overhears a telephone conversation between the Fitzgibbonses' patriarch and the staff of NIMH and learns that the institute intends to exterminate the rats in the morning. Brisby then escapes from the cage and runs off to warn them. As a thunderstorm approaches, the rats begin moving the Brisby home, with the children and Auntie Shrew inside, using a rope and pulley system. Jenner sabotages the assembly, causing it to fall apart and crush Nicodemus to death. Brisby soon arrives to warn the rats about NIMH's arrival, but Jenner attacks her and attempts to steal the amulet as his reluctant accomplice, Sullivan, alerts Justin, who comes to Brisby's aid. Jenner mortally wounds Sullivan and engages Justin in a sword fight, but is killed by a knife in the back from the dying Sullivan. The Brisby home begins to sink into the muddy ground and Brisby and the rats are unable to raise it. All appears lost until Brisby's will to save her family suddenly gives power to the amulet, which she uses to lift the house and move it to safety. The next day, the rats, with Justin as their new leader, have departed for Thorn Valley as Timothy begins to recover, while Jeremy meets and falls in love with an equally clumsy female crow.

The story is set in Japan, beginning in the early 1990s up until the present day (2008), with each act centered on a boy named Takaki Tōno.

In a sleepy village in Italy, Jiminy Cricket arrives at the shop of a woodworker and toymaker named Geppetto, who lives with his pet cat Figaro and fish Cleo creates a puppet he names Pinocchio. As he falls asleep, Geppetto wishes upon a star for Pinocchio to be a real boy. Late that night, the Blue Fairy visits the workshop and brings Pinocchio to life, although he remains a puppet. She informs him that if he proves himself to be brave, truthful, and unselfish, he will become a real boy. When Jiminy reveals himself, the Blue Fairy assigns him to be Pinocchio's conscience. Geppetto awakens upon hearing the commotion from Pinocchio falling, and is overjoyed to discover that he is alive and will become a real boy. The next morning, while walking to school, Pinocchio is led astray by con artist fox Honest John and his sidekick Gideon the Cat. Honest John convinces him to join Stromboli 's puppet show, despite Jiminy's protestations. Pinocchio becomes Stromboli's star attraction, but when he tries to go home, Stromboli locks him in a bird cage and leaves to tour the world with Pinocchio. After Jiminy unsuccessfully tries to free his friend, the Blue Fairy appears, and an anxious Pinocchio lies about what happened, causing his nose to grow and become a tree branch with a bird's nest. The Blue Fairy restores his nose and frees Pinocchio when he promises to make amends, but warns him that she can offer no further help. Meanwhile, a mysterious Coachman hires Honest John to find disobedient and naughty boys for him to take to Pleasure Island, a notorious and infamous place. Honest John, despite the legal risks and the Coachman's implication of what happens to the boys, accepts the job out of fear, and finds Pinocchio, persuading him to take a vacation on Pleasure Island. On the way to the island, Pinocchio befriends Lampwick, a delinquent boy. At Pleasure Island, without rules or authority to enforce their activity, Pinocchio, Lampwick, and many other boys soon engage in vices such as vandalism, fighting, smoking and drinking. Jiminy eventually finds Pinocchio in a bar smoking and playing pool with Lampwick, and the two have a falling out after Pinocchio defends Lampwick for his actions. As Jiminy tries leaving Pleasure Island, he discovers that the island hides a horrible curse that transforms the boys into donkeys after making "jackasses" of themselves, and they are sold by the Coachman into slave labor. Pinocchio witnesses Lampwick transform into a donkey, and with Jiminy's help, he flees before he can be fully transformed himself, though he still has a donkey's ears and tail. Upon returning home, Pinocchio and Jiminy find Geppetto's workshop deserted, and obtain a letter from the Blue Fairy in the form of a dove, stating that Geppetto had set out to sea in search for Pinocchio on Pleasure Island, but got swallowed by a gigantic and vicious sperm whale called Monstro and is now trapped in its belly. Determined to rescue his father, Pinocchio jumps into the Mediterranean Sea with Jiminy and is soon swallowed by Monstro, where he reunites with Geppetto. Pinocchio devises a scheme to make Monstro sneeze and allow them to escape, but the whale chases them and destroys their raft with his tail. Pinocchio selflessly pulls Geppetto to safety in a cove just as Monstro crashes into it and he and Pinocchio are killed in the process. Back at home, Geppetto, Jiminy, Figaro, and Cleo mourn Pinocchio. Having succeeded in proving himself brave, truthful, and unselfish, Pinocchio is revived and turned into a real human boy by the Blue Fairy, much to everyone's joy. As the group celebrates, Jiminy steps outside to thank the Fairy and is rewarded with a solid gold badge that certifies him as an official conscience.

In an English village in the 1800s, Victor Van Dort, the son of nouveau riche fish merchants, and Victoria Everglot, the neglected daughter of impoverished aristocrats, prepare for their arranged marriage, which will simultaneously raise the social class of the Van Dort family and restore the wealth of the Everglot family ("According to Plan"). Although the two are initially nervous, they become smitten and fall in love instantly when they meet; however, the nervous Victor ruins their wedding rehearsal by forgetting his vows, dropping the ring, and accidentally setting Lady Everglot's dress on fire. Fleeing to a nearby forest, Victor successfully rehearses his vows with a tree and places his wedding ring on what appears to be an upturned root. However, the "root" is revealed to be the skeletal finger of a deceased woman named Emily, who, gowned in a wedding dress, rises from the grave and proclaims herself as Victor's new wife. She spirits them both away to the Land of the Dead, a colorful and whimsical realm in which the spirits of the deceased reside. During his time with Emily, Victor learns that she was murdered years earlier on the night of her elopement by her fiancé, who stole the family jewels and gold she had brought (" Remains of the Day "). She reunites him with his long-dead dog Scraps, and they bond. However, desperate to return to Victoria, Victor tricks Emily into returning them to the Land of the Living by claiming he wants her to meet his parents. Emily brings Victor to see Elder Gutknecht, the kindly ruler of the underworld, who grants them temporary passage. Victor reunites with Victoria and confesses his wish to marry her as soon as possible. Before they can share a kiss, Emily discovers them and drags Victor back to the Land of the Dead, feeling betrayed and hurt ("Tears to Shed"). Victoria tries to tell her parents and the village pastor of Victor's situation, but nobody believes her. Assuming Victor has left her, Victoria's parents decide to marry her against her will to Lord Barkis Bittern, a presumed-wealthy visitor who appeared at the wedding rehearsal. After reconciling with Emily, Victor learns of Victoria's impending marriage to Barkis from his family's newly deceased coachman Mayhew. Upset over this news, he decides to marry Emily properly after overhearing Elder Gutknecht tell her that due to Victor still being alive while she is dead, her accidental marriage to Victor is nullified by default. He knows that this will require him to repeat his wedding vows with her in the Land of the Living and drink the poison 'the Wine of Ages' in order to join Emily in death. The dead swiftly prepare for the ceremony and head "upstairs" ("The Wedding Song"). There, the village erupts into a temporary panic upon their arrival, until the living recognize their departed loved ones and joyously reunite with them. The chaos causes a panicked Barkis to expose his own poor financial standing and his intentions to marry Victoria only for her supposed wealth, leading her to reject him. Victoria witnesses Victor and Emily's wedding as Victor completes his vows and prepares to drink the poison, only for Emily to stop him when she realizes she is denying Victoria her chance to live happily with him. Just as Emily reunites Victor and Victoria, Barkis arrives to kidnap Victoria; Emily recognizes Barkis as both her previous fiancé and murderer. Victor duels with Barkis to protect Victoria, and Emily intervenes to save Victor's life. Accepting defeat, Barkis mockingly toasts Emily for dying unwed and unwittingly drinks the poison, causing him to die. This allows the dead – who cannot interfere in the affairs of the living – to take retribution against him for his crimes. Emily, now freed from her torment, releases Victor of his vow to marry her and returns his ring, so he can marry Victoria. As she steps into the moonlight, she dissolves into a swarm of butterflies that fly into the sky as Victor and Victoria watch and embrace.
