In Reed College, in 1974, the high tuition costs force Steve Jobs to drop out, but Dean Jack Dudman allows him to sit in on classes. Jobs is particularly interested in a calligraphy course. Influenced by Baba Ram Dass 's book Be Here Now and their experiences with LSD, Jobs and his friend Daniel Kottke spend time in India. His philosophical ideas lead Jobs to the decision not to wear any footwear. Two years later, Jobs is back in Los Altos, California, living with his adoptive parents Paul and Clara. While working for Atari, Inc. as a video game developer, Jobs develops a partnership with his friend Steve "Woz" Wozniak. Jobs is charged by his boss Al Alcorn to re-develop arcade video game Breakout, which he ends up having Wozniak build in his place. The job is such a success that Alcorn presents it to President Nolan Bushnell, but Jobs inequitably distributes the salary for Breakout 's development between Wozniak and himself. Later, Jobs discovers that Wozniak built a prototype for the Apple I, a " personal home computer " which he expresses interest in commercializing. They name their new company Apple Computer. After a failed sale at his employer company HP, Wozniak reluctantly demonstrates the Apple I at the Homebrew Computer Club to a bored audience. Jobs is later approached by store owner Paul Terrell who shows interest in the Apple I. Jobs persuades his father Paul to let them set up their new company in the family's garage workshop. Jobs also recruits Kottke, fellow engineer Bill Fernandez, and young neighbor Chris Espinosa to the Apple team. Terrell's disappointment in the Apple I (in his opinion, being only a motherboard and not a full computer as promised), inspires Jobs to restart with a second model. He hires Rod Holt to re-conceptualize the power supply for what will be called the Apple II. Venture capitalist Mike Markkula notices Jobs and Wozniak's work, and also joins Apple. The Apple II is released at the 1977 West Coast Computer Faire, where it is a success. Apple's success causes Jobs to distance himself from his friends. Upon learning that his high-school girlfriend Chrisann Brennan is pregnant, Jobs ends their relationship. Brennan gives birth to Lisa, whom Jobs denies is his child. Kottke (now an Apple II Plus repairer) meanwhile leaves the company after acknowledging that Jobs (who hardly even has any time to talk to him) is not rewarding the Apple I team with any Apple stock. John Sculley is recruited as CEO of the company. As Jobs' behavior grows more erratic, Jobs is moved from the Apple Lisa development team to the Macintosh Group, where he works with Bill Atkinson, Burrell Smith, Chris Espinosa, and Andy Hertzfeld. Despite the change, his behavior does not change: he forces out Jef Raskin, the original Macintosh group leader, and then takes his place. Later, he phones Microsoft founder Bill Gates, legally threatening him because their Word software is, in his opinion, a plagiarism of Apple's word processor. Wozniak, still part of the Apple IIe team, decides to leave the company, feeling that it has lost its way. Though the Macintosh is introduced with great fanfare in 1984, including a high-budget commercial, it is seen as a failure due to the disproportionately high cost (as compared to IBM PC compatibles). Jobs, convinced that the error is the limited random-access memory of the system, launches a more advanced version, but Sculley forces him out of the company in 1985. In 1996, Jobs is married to Laurene Powell and has accepted Lisa as his daughter (she now lives with them). He has a son, Reed, and also runs NeXT. When Apple buys NeXT, then-CEO Gil Amelio asks Jobs to return to Apple as a consultant. Jobs is named the new CEO, fires Amelio and relieves the Board of Directors. Jobs becomes interested in the work of Jony Ive, particularly during the design of the iMac and strives to reinvent Apple. Jobs later records the dialogue for the Think Different commercial in 1997. In 2001, Steve Jobs introduces the iPod at an Apple Town Hall meeting.

Brian Reader is a former thief who is now retired. At the funeral ceremony for his wife Lyn, Brian sees old friends from his days as a criminal. They briefly discuss their interest in pulling off one more heist, targeting the Hatton Garden Safe Deposit. Shortly after the funeral, Brian and the other thieves meet to plan the robbery in earnest. Nearly all of them are older men, in their 60s and 70s. The only younger man is Basil, an alarms expert who comes by a key to an exterior door of the building containing the Safe Deposit. The thieves decide to execute their heist over the Easter holiday weekend to maximise their time for the break-in and minimise the risk of being discovered. Posing as gas repairmen, they enter the deposit building, deactivate the alarms by trial and error, and proceed to drill a hole into the wall of the vault. The jack they use to push the cabinet of safety deposit boxes away from the wall breaks, adding a wrinkle to their plan. They all leave, intending to return with a new tool the following day. However, Brian has a change of heart and decides it is too risky to go back. Basil meets with Brian to try and convince him to go back and finish the robbery. Brian refuses, but gives Basil a note listing the safety deposit boxes that contain the most valuable diamonds. In return, Basil promises to give Brian half of his take from the robbery. Basil and the other thieves return to the Safe Deposit with the replacement tool and successfully push the cabinet away from the vault wall, enabling two of them to climb through into the vault. They then use crow bars to break open many of the safety deposit boxes and steal their contents, which add up to more than £14 million in jewels and cash. The thieves put all of the loot into duffel bags and drive away from the scene of the crime. They proceed to the home of one of the robbers to split up the stolen goods. As they begin to discuss the split, Basil realises that the older thieves were never planning on giving him an equal share. Fearing for his life, he takes several fistfuls of cash and quickly leaves. What the other thieves do not realise until later is that Basil had also taken the high value diamonds from the safety deposit boxes that Brian had written down for him. Meanwhile, the police are alerted to the crime and begin a high-profile investigation. They review all CCTV footage from the area and soon discover a car parked in the area that belonged to one of the thieves. After tracing the car's number-plate to the thief's actual identity, the police are able to tap all of the gang's phones and follow their movements. After learning of the value of the loot, Brian tries to force the group to split with him since he was the one who masterminded the robbery. As the thieves grow increasingly wary and distrustful of one another, they have a number of unguarded conversations that provide the police with evidence of their culpability. By further spying on the gang, the police learn that the group is planning to meet in order to do a final split of the stolen goods. The police move in and arrest the gang at their meeting. Brian, who was not invited to the meeting, is arrested at his home. The only one to escape is Basil as he wore a disguise during the robbery, left shortly after the Easter weekend, and was never a former associate of the older thieves. At the end, the old thieves are in custody and they are shown changing into suits for their court appearance. They seem unconcerned about the prospect of returning to jail and appear to have accepted Brian Reader as their unspoken leader once again.
