Disney's classic first venture into the field of computer-generated animation. Whizz-kid computer programmer Kevin Flynn (Jeff Bridges) tries to hack into the ENCOM computer system, but his efforts are continually frustrated by the Master Control Program. One night he is actually transported into the system, where he again comes up against the oppressive totalitarian forces of the Master Control Program, and realises that his best chance of survival in this virtual world is to set out in search of the security program TRON.
