“You can't steal something that's designed to be free.”
―Sam Flynn
Sam Flynn is the protagonist of the 2010Disney film Tron: Legacy. He is the son of Kevin Flynn and Jordan Canas-Flynn and the controlling shareholder of ENCOM.
Ever since Kevin and Jordan died, Sam has been deeply affected by the loss of his parents. He is also the heir to the largest software company in the world, which makes him feel he can't follow in his father's footsteps. He is somewhat rebellious, reclusive, and lives modestly with his pet dog, Marv, in a shipping container reconstituted into a home on the river with a beautiful view of the city and the ENCOM Tower itself. He has a pronounced technical aptitude inherited from his father and has applied this toward fixing Kevin's motorcycle.
As a kid, Sam loved to listen to Flynn's stories about Tron and the Grid, even collecting the merchandise based on them. After Flynn's disappearance, he was raised by his grandparents, as his mother had already passed beforehand. By age 27, Sam had lost his grandparents and lived in a shabby apartment below the bridge with his dog, Marv. He also grew to be a thrill-seeker as he performed dangerous stunts during his annual pranks on ENCOM. He did this because he lacked interest in the company otherwise. However, he had hardened to the thought of his father returning; believing him to be dead or living peacefully on a tropical island.
However, his father's best friend and work associate, Alan Bradley, informed him that he received a page from Flynn's arcade, which had been closed for twenty years. Sam investigated and found Flynn's lab. However, he accidentally zapped himself into the Grid, where he was mistaken for a damaged program and forced into the Games. However, his opponent, Rinzler, noticed he bled and recognized him as a User. Sam was then brought before CLU (who at first put on the charade of being Flynn due to their resemblance), who thought he would have the information on his Identity Disc to free him from the Grid. However, this proved not to go in CLU's favor, and Sam was forced onto the Light Cycle arena. Sam was nearly killed by CLU but was rescued by a program named Quorra.
Escaping with Quorra, Sam reunited with his father, who enlightened him as to why he had been trapped in the Grid for 20 years. Deciding to return home rather than listen to his father and stay to keep CLU from getting what he wanted, Sam went to Tron City to meet one of Quorra's old acquaintances, Zuse. However, Zuse proved to be a backstabber and turned Sam over to CLU's guards. Luckily, Quorra and Flynn arrived and rescued him, but lost Flynn's disc to Zuse. Sam then boarded a transport heading to the exit portal. On board while conversing with his father about everything that happened in the real world since entering the Grid, he learned Quorra was the last ISO and that she was needed on the outside. When the transport arrived at CLU's re-purposing area, Sam took back Flynn's disc, and they stole a flying vehicle to escape. Reaching the portal, Sam was forced by his father to leave with Quorra, while CLU was destroyed. Back in the real world, Sam downloaded the Grid onto a chip and keeps it. Deciding to take responsibility of ENCOM, he names Alan Chairman of the Board and takes Quorra to see her first sunrise. Throughout the movie, Sam is shown to have a growing attraction to Quorra.
