Plot

In 1983, a high-tech, highly realistic adult amusement park called Delos features three themed "worlds": Western World (the American Old West), Medieval World (medieval Europe) and Roman World (the ancient Roman city of Pompeii). The resort's three "worlds" are populated with lifelike androids that are practically indistinguishable from human beings, each programmed in character for their historical environment. For $1,000 per day, guests may indulge in any adventure with the android population of the park, including sexual encounters and a simulated fight to the death. Delos's tagline in its advertising promises "Boy, have we got a vacation for you!"
