A few years after the disaster at the Westworld theme park, owner Duffy (Arthur Hill) revamps his property into an amazing new recreational destination and calls it Futureworld, but investigative reporters Chuck (Peter Fonda) and Tracy (Blythe Danner) remain skeptical of the park’s wonders. It isn't long before the pair uncovers a diabolical plot in this sequel to the 1973 thriller Westworld, whose original star Yul Brynner makes a cameo here.
