In the then-future year of 1983, a high-tech, highly realistic adult amusement park called Delos features three themed worlds: Western World, Medieval World, and Roman World. 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.
