Plot
In 1999 Los Angeles, Hannon Fuller (Mueller-Stahl) owns a multibillion-dollar computer enterprise and is the inventor of a newly completed virtual reality (VR) simulation of 1937 Los Angeles, filled with simulated humans unaware they are computer programs. When Fuller is murdered just as he begins premature testing of the VR system, his friend and protégé, Douglas Hall (Bierko), who is also the heir to the company, becomes the primary suspect. The evidence against him is so strong that Hall begins to doubt his own innocence.
Between interrogations by LAPD Detective Larry McBain (Haysbert), Hall meets Jane Fuller (Gretchen Mol), the estranged daughter of Hannon Fuller, who is busy with the shutdown of the new VR system. Hall then romances her. When a local bartender is murdered after he claims to have witnessed a meeting between Hall and Fuller on the night Fuller was murdered, Hall is arrested. He is released when Jane gives him an alibi.
With the assistance of his associate Whitney (D'Onofrio), Hall attempts to find a message that Fuller left for him inside the simulation. Entering the virtual reality, Hall becomes a bank clerk named John Ferguson. Fuller left the message with a bartender named Jerry Ashton (D'Onofrio), who read the message and discovered he is an artificial creation. Earlier, Ashton notices that Ferguson switched places with Hall in the men's restroom of the hotel where Ashton works, and began to realize that something was wrong. Frightened and angry, Ashton tries to kill Hall. Hall barely survives to escape the VR.
