It is sometime in the near future, in a fictional high-tech adult amusement park called Delos. The park is divided into three zones: WesternWorld, MedievalWorld and RomanWorld. The entertainment in all three areas consists primarily of interaction by the guests with androids programmed to act in character (the Old West, medieval Europe, and pre-Christian Rome, respectively). The androids are indistinguishable from human beings, apart from minor flaws in their hands, and guests are encouraged to indulge in any fantasy, including killing the androids.

In what may be the first mention of the concept of a computer virus in a film, the technical staff describe inexplicable problems and breakdowns spreading "like a disease" between the machines, first in one area of the park and then on to the others. First, the robots in MedievalWorld begin suffering an inexplicable number of systemic failures. Then, a robot rattlesnake strikes Blane. Against her programming, a female servant android refuses a guest's request for sex. The failures increase until the robotic Black Knight kills a guest in a sword-fight in MedievalWorld. The resort's supervisors, in increasing desperation, attempt to regain control by shutting down power to the entire park. Unfortunately, this results in trapping them...
