Tron is a 1982 American action science fiction film produced by Walt Disney Pictures. It stars Jeff Bridges as the protagonist hacker Kevin Flynn (and his program counterpart inside the electronic world, CLU), Bruce Boxleitner as Tron (and Tron's "user", Alan Bradley), Cindy Morgan as Yori (and her "user", Dr. Lora Baines), and Dan Shor as Ram. David Warner plays all three main antagonists: the program Sark, his "user", Ed Dillinger, and the voice of the Master Control Program. Tron was written and directed by Steven Lisberger, who has a distinctive visual style, as it was one of the first films from a major studio to use extensive computer graphics. Decades after it first came out, it has spawned a franchise consisting of a sequel film, multiple video games, comic books and a planned television series.
Before the beginning of the film, Kevin Flynn (Jeff Bridges) is a young and gifted software engineer who works for the software corporation ENCOM, creating several video games on the company's mainframe after hours, aiming to start his own game company. However, another programmer named Ed Dillinger (David Warner) locks Flynn out of the system and presents Flynn's work as his own. Dillinger earns himself a series of executive promotions, while Flynn is relegated to opening a video game arcade, featuring the games that he created. From then to the present, Flynn tries to hack into the ENCOM 511 mainframe to find evidence of Dillinger's wrongdoing, but his program, Clu, is caught and erased by the Master Control Program (MCP), an artificial intelligence running on the ENCOM computer system.
The MCP, with Dillinger's authorization, shuts down access to the security group Flynn is using, inadvertently locking out another ENCOM employee, Alan Bradley (Bruce Boxleitner). Alan goes to speak to Dillinger and reveals that he was working on a security program, Tron, which would monitor communications between the MCP and the outside world. After Alan leaves, the MCP confronts Dillinger about this, stating that it cannot afford to have programs monitoring it. It reveals its intention to break into the Pentagon and other military mainframes, claiming it can run things "900 to 1200 times better than any human." When Dillinger attempts to assert his authority, the MCP essentially blackmails him into complying with its wishes.
Meanwhile, Alan and his girlfriend, Dr. Lora Baines (Cindy Morgan), go to warn Flynn that he has been noticed. Explaining what happened, Flynn convinces them to sneak him into ENCOM's laser laboratory, where he can access the mainframe via a different security group. Lora, who has been developing a method of digitizing real objects into the computer, sets Flynn down at her terminal in the laser lab, where a laser is pointed directly at the terminal. As Flynn attempts to break into the system, he is confronted by the MCP, who takes control of the laser and suddenly digitizes Flynn into the ENCOM mainframe. Flynn finds himself standing in the digital world, where Programs resemble their human creators, the Users.
