Pirates of Silicon Valley

Steve Jobs (Noah Wyle) is speaking with director Ridley Scott (J. G. Hertzler), about the creation of the 1984 commercial for Apple Computer, which introduced the first Macintosh. Jobs is trying to convey his idea that "We're creating a completely new consciousness." Scott is more concerned with the technical aspects of the commercial.
Next in 1997 with Jobs, returning to Apple, and announcing a new deal with Microsoft at the 1997 Macworld Expo. His partner, Steve Wozniak or "WOZ" (Joey Slotnick), is introduced as one of the two central narrators of the story. Wozniak notes to the audience the resemblance between Big Brother and the image of Bill Gates (Anthony Michael Hall) on the screen behind Jobs during this announcement. Asking how they "got from there to here," the film turns to flashbacks of his youth with Jobs, prior to the forming of Apple.
The earliest flashback is in 1971 and takes place on the U.C. Berkeley campus during the period of the student anti-war movements. Teenagers Steve Jobs and Steve Wozniak are shown caught on the campus during a riot between students and police. They flee and after finding safety, Jobs states to Wozniak, "Those guys think they're revolutionaries. They're not revolutionaries, we are." Wozniak then comments that "Steve was never like you or me. He always saw things differently. Even when I was in Berkeley, I would see something and just see kilobytes or circuit boards while he'd see karma or the meaning of the universe.
Using a similar structure, the film next turns to a young Bill Gates at Harvard University, in the early 1970s, with classmate Steve Ballmer (John DiMaggio), and Gatesâ high school friend Paul Allen (Josh Hopkins). As with Wozniak in the earlier segment, Ballmer narrates Gates' story, particularly the moment when Gates discovers the existence of Ed Roberts's MITS Altair causing him to drop out of Harvard. Gates' and Allen's early work with MITS is juxtaposed against the involvement of Jobs and Wozniak with the "Homebrew Computer Club". Jobs and Woz develop Apple Computer in the garage of Jobs' family home, with the help of Daniel (Marcus Giamatti) and Elizabeth (Melissa McBride). Eventually Mike Markkula (Jeffrey Nordling) invests in the company which allows it to expand and move forward. In 1977, Jobs, Woz, and Markkula demo the Apple II at the West Coast Computer Faire. This event is followed by the development of the IBM-PC with the help of Gates and Microsoft in 1981.
The film also follows Jobs' relationship with his high school girlfriend and early Apple employee, Arlene (a pseudonym for Chrisann Brennan, portrayed by Gema Zamprogna, and the difficulties he had acknowledging the birth and existence of their daughter, Lisa. Around the time his daughter was born, Jobs unveiled his next computer, which he named, The Lisa. The Lisa was then followed in 1984 by the (Macintosh), a computer inspired by the Xerox Alto. The main body of the film finally concludes with a 30th birthday toast in 1985 to Steve Jobs shortly before he was fired by CEO John Sculley (Allan Royal), from Apple Inc.
The film ends in 1997, with 42 year old Jobs' return to Apple (after its acquisition of NeXT Computer) and with his announcement at the MacWorld Expo of an alliance between Apple and Microsoft. It also indicates that Jobs is now married, has children, and has reconciled with Lisa.
