The film opens with a pre-taped sketch depicting a scene from Murphy's childhood. At a family Thanksgiving in November 1968, the children take turns showing their talents to the assembled relatives (including one played by Murphy himself). Young Eddie (Deon Richmond) shocks the family with a rude joke about a monkey and a lion. While the rest of the adults are shocked, his aunt and uncle are delighted and the uncle (Samuel L. Jackson) proclaims, "I love that doo-doo line. That boy's got talent!" After emerging on stage for the live show, Murphy begins by discussing the angry reactions of celebrities parodied in his previous stand-up show, Delirious, specifically Mr. T and Michael Jackson, as well as homosexual viewers offended by his jokes about " faggots." Murphy then narrates a phone call he received from Bill Cosby chastising him for using profanity on stage. Angered by Cosby's assumption that his entire act was nothing but "filth flarn filth," Murphy calls Richard Pryor for advice. Pryor declares that his only concerns should be making audiences laugh and getting paid, and recommends that he tell Cosby to " Have a Coke and a smile and shut the fuck up." Murphy elaborates on his admiration for the "raw" comedy of Pryor, running through a routine from his own teenage years about defecation, in Pryor's voice. He then goes on to talk about how people who don't speak English only pick up the curse words in his act, and shout them at him on the street. Next comes a lengthy routine about dating and relationships. Murphy explains that the rise of deadly sexually transmitted infections has motivated him to seek marriage, but the divorce of Johnny Carson and Joanna Holland (in which she sought 50% of his assets) has left him paranoid about the financial risk of marriage, concluding that "no pussy is worth $150 million." He mocks the aggression and materialism of American women (compared to his belief in the meekness of Japanese women), referring to the popularity of Janet Jackson 's song " What Have You Done for Me Lately." He jokes that he intends to go deep into Africa to find a "bush bitch" who has no concept of Western culture... at least until American women convince her to stand up for herself and demand "HALF!" This develops into a broader warning to men to avoid "the pussy trap," and a warning to women that men never remain faithful — once a man has evoked a powerful orgasm from a woman ("ooohhhh!") she will tolerate all kinds of misbehavior, although she may pursue infidelity of her own. The next segment narrates a childhood memory of his mother promising to cook him a hamburger "better than McDonald's," only to produce an unappealing "big, welfare, green-pepper burger," a lump of beef filled with onion and green peppers on Wonder Bread (while the neighborhood children show off their McDonald's hamburgers in a call-back to the ice cream segment of Delirious), but he states that as an adult, he has more of an appreciation of the tastiness of his mom's homemade dish. Murphy then talks about white people out on the town, criticizing their embarrassing dance moves, leading onto Italian-Americans being inspired by Rocky, then culminates to a bit about fighting in a discotheque with Deney Terrio, eventually starting a large-scale brawl after which "everybody sued me" for millions of dollars. After the fight, Murphy calls his parents, leading to a long impression of his drunken stepfather (another call-back to a popular bit from Delirious). This final segment runs for over ten minutes and incorporates his stepfather's habit of misquoting Motown songs (including "Ain't Too Proud to Beg", which opened the film).

The documentary uses genuine footage and audio recorded at the time of the accident on the divers' voice communications equipment and helmet cameras, supplemented with interviews of several of the individuals involved, as well as some reconstructed footage, to tell the story of the accident. Chris Lemons, along with his colleagues Duncan Allcock and David Yuasa, were carrying out repairs 100 metres (330 ft) below the surface of the North Sea, supported by the support vessel Bibby Topaz. The vessel's dynamic positioning system, supplied by Kongsberg Maritime, failed. This caused the vessel to drift in rough seas, dragging the divers away from the area they were working and eventually snapping the umbilical tether that provided Lemons with heliox breathing gas, as well as hot water to heat his suit, power for his light, and a communications link to the bell and surface. He was left with only five minutes supply of breathable gas contained in the emergency gas supply cylinders he carried on his back. For reasons that are unclear to Lemons and his colleagues, but attributed in part to the cold water and having been breathing a gas mix with a high partial pressure of oxygen, Lemons survived for around 30 minutes while he was located by a remotely operated underwater vehicle and then by Yuasa, who was able to pull him back onboard the diving bell.
