A computer hacker is abducted into a digital world and forced to participate in gladiatorial games where his only chance of escape is with the help of a heroic security program.

Hacker/arcade owner Kevin Flynn is digitally broken down into a data stream by a villainous software pirate known as Master Control and reconstituted into the internal, 3-D graphical world of computers. It is there, in the ultimate blazingly colorful, geometrically intense landscapes of cyberspace, that Flynn joins forces with Tron to outmaneuver the Master Control Program that holds them captive in the equivalent of a gigantic, infinitely challenging computer game.

Sam Flynn, the tech-savvy 27-year-old son of Kevin Flynn, looks into his father's disappearance and finds himself pulled into the same world of fierce programs and gladiatorial games where his father has been living for 20 years. Along with Kevin's loyal confidant Quorra, father and son embark on a life-and-death journey across a visually-stunning cyber universe that has become far more advanced and exceedingly dangerous. Meanwhile, the malevolent program CLU, who dominates the digital world, plans to invade the real world and will stop at nothing to prevent their escape.
