An amusement park for rich vacationers. The park (Delos Park-Westworld, Medieval World, Roman World) provides its customers a way to live out their fantasies through the use of robots that provide anything they want. Two of the vacationers choose a wild west adventure - Westworld. However, after a computer breakdown, they find that they are now being stalked by a rogue robot gun-slinger.
