Computer scientist Hannon Fuller has discovered something extremely important. He's about to tell the discovery to his colleague, Douglas Hall, but knowing someone is after him, the old man leaves a letter in his computer generated parallel world that's just like the 30's with seemingly real people with real emotions. Fuller is murdered in our real world the same night, and his colleague is suspected. Douglas discovers a bloody shirt in his bathroom and he cannot recall what he was doing the night Fuller was murdered. He logs into the system in order to find the letter, but has to confront the unexpected. The truth is harsher than he could ever imagine...

The science fiction novel Simulacron-3 was also published under the title Counterfeit World, it was first published in 1964 by Daniel F. Galouye in the United States, and is one of the first literary descriptions of virtual reality.

Jason Whitney/Jerry Ashton:
Hey! What'd you do to the world?


Douglas Hall:
Turned it off.

Incorrectly regarded as goofs: In the 1937 world, the old man (Fuller) refers to World War I. There had been no World War II yet, thus World War I should have been referred to as "The Great War", but since the world was actually a simulation, this is just an error in the simulation. Many other anachronisms in the 1937 world can be similarly explained, such as the too-new money and a too-new police car.
