The Delos Corporation was the world's largest and most powerful multi-national company. Among its many enterprises was the futuristic amusement park, Westworld, where visitors were waited on by sophisticated robots that looked and acted like real human beings. With their help, Westworld's visitors could live out their wildest fantasies.

Enter the mad scientist, Simon Quaid, who with Joseph Oppenheimer, had invented these life-like robots for Delos. Quaid, an unstable genius, decided to reprogram his inventions to take over the world and turn it into a "utopian" society under his rule. John Moore, head of Delos Security, and his beautiful assistant, Pamela Williams, were the two that found out about and foiled this fiendish plot.

Beyond Westworld was a spin-off of sorts to the 1973 movie Westworld, in which the robots ran amok and destroyed the amusement park, killing almost all of the guests in the process. Yul Brynner, as one of the robots, was the star of the movie and was its only cast member to appear in its sequel, Futureworld.
