Mulder and Scully investigate the murder of three programmers and a security guard at the Forbin Gaming Co. in California, a development company for computer and virtual reality games. The killer, Robert Capek, claims that a computer program controlled him and made him commit the murders. They find that the team was working on Project Praetorius, which was developing virtual reality games with simulated characters that could experience emotions.
When Mulder & Scully go to interview Capek, they find that since initial consultation with his lawyer, he has only been able to make strange sounds that resemble noises made by electronic equipment. X reveals to Mulder that the Forbin Company has been developing software for military use. An online friend of Capek's tells the two agents that Capek was furious that Project Praetorius was going to be used by the military, and wanted to steal the program. One method he thought of was to transfer the binary code into audio impulses that could be stored in his brain.
When they take recordings of the sounds Capek makes to the Lone Gunmen, the sounds are found to be binary code that reveal both text and images—the computer program's perspective of the murders. The program says that it is unhappy when it sees that Capek has killed its "family," and it is implied that the program is slowing killing Capek because of this.
