Output: In 1989, seven years after the events of the first film, Kevin Flynn, who has been recently promoted CEO of ENCOM International, disappears. Twenty years later, his son Sam, now ENCOMs primary shareholder, takes little interest in the company beyond playing an annual prank on its board of directors. After being freed from police custody for his most recent prank, Sam is asked by Alan Bradley, an ENCOM executive and Flynns old friend, to investigate a strange pager message originating from Flynns shuttered video arcade. Sam discovers a large computer in a hidden basement, which suddenly teleports him to the Grid, a virtual reality created by Flynn that exists within ENCOM’s computer mainframe. He is quickly captured and sent to the Games, where he is forced to fight a masked program named Rinzler. When Sam is injured and begins bleeding, Rinzler realizes that Sam is a human User and takes him before Clu, the Grids corrupt ruling program who resembles a younger Kevin Flynn. Clu nearly kills Sam in a Light Cycle match, but Sam is rescued by Quorra, an apprentice of Flynn, who conveys him to his fathers hideout outside Clus territory. Flynn reveals to Sam that he had been working to create a perfect computer system and had appointed Clu and Tron a security program created by Bradley its cocreators. During this construction, the trio discovered a species of naturally occurring isomorphic algorithms ISOs not conceived by Flynn, bearing the potential to resolve various mysteries in science, religion and medicine. Clu, considering them an aberration, betrayed Flynn, seemingly killed Tron, and destroyed the ISOs. Meanwhile, the Portal permitting travel between the two worlds had closed, leaving Flynn trapped in the system. Having gained complete control, Clu sent the message to Alan in order to lure Sam onto the Grid and reopen the Portal for a limited time. As Flynns identity disc is the master key to the Grid and the only way to traverse the Portal, Clu expects Sam to bring Flynn to the Portal so he can take Flynns disc, go through the Portal himself, and impose his idea of perfection on the human world. Against his fathers wishes, Sam returns to Clus territory on Quorras tipoff to find Zuse, a program who can provide safe passage to the Portal. At the End of Line Club, its owner Castor reveals himself to be Zuse, then betrays Sam to Clus guards. In the resulting fight, Flynn rescues his son, but Quorra is injured and Zuse gains possession of Flynns disc. Zuse attempts to bargain with Clu for the disc, but Clu simply takes the disc and destroys the club along with Zuse. Flynn and Sam stow away aboard a solar sailer transport program, where Flynn restores Quorra and reveals her to be the last surviving ISO. The transport is intercepted by Clus warship; as a diversion, Quorra allows herself to be captured by Rinzler, whom Flynn recognizes as Tron, reprogrammed by Clu. Sam reclaims Flynns disc and rescues Quorra, while Flynn takes control of a Light Fighter on the flight deck. Clu, Rinzler, and several guards pursue the trio in Light Jets. Upon making eye contact with Flynn, Rinzler remembers his past and deliberately collides with Clus Light Jet, but Clu uses Trons spare baton to escape while Tron falls into the Sea of Simulation below. Clu confronts the others at the Portal, where Flynn reintegrates with his digital duplicate, destroying Clu along with himself. Quorra, having switched discs with Flynn, gives Flynns disc to Sam and they escape together to the real world. In Flynns arcade, Sam backs up and deactivates the system. He then finds a waiting Bradley and tells him he plans to retake control of ENCOM, naming Bradley chairman of the board. He departs on his motorcycle with Quorra, and she witnesses her first real sunrise.
