While working between robberies, on Andy Miller's Wyoming ranch, Butch Cassidy and the Sundance Kid learn of the Riders, who are plaguing their host with wild and seemingly pointless shoot-outs. It seems that Sundance's sister, deranged by jealousy, has hired the Riders - led by the sadistic Joshua Pitt - to end the Kid's days. When the mysterious gunmen attack the ranch again, murdering Miller's son and taking Butch hostage, the Kid follows their deliberately laid trail...
