Reporters investigating a hi-tech theme park discover a sinister plot to take over the planet using robotic lookalikes of world leaders. Sci-fi sequel to Westworld, starring Peter Fonda, Blythe Danner, Arthur Hill and Yul Brynner.

Two years after the Westworld tragedy in the Delos amusement park, the corporate owners have reopened the park following over $1 billion in safety and other improvements. For publicity purposes, reporters Chuck Browning and Tracy Ballard are invited to review the park. Just prior to arriving, however, Browning is given a clue by a dying man that something is amiss.
