Interest in creating a sequel to Tron arose after the film garnered a cult following. The story follows Flynn's adult son Sam, who responds to a message from his long-lost father and is transported into a virtual reality called 'the Grid', where Sam, his father, and the algorithm Quorra must stop the malevolent program Clu from invading the real world.

It serves as a sequel to Tron (1982), whose director Steven Lisberger returned to produce.
