Vietnam veteran and drifter John J. Rambo (Sylvester Stallone) wanders into a small Washington town in search of an old friend, but is met with intolerance and brutality by the local sheriff, Will Teasle (Brian Dennehy). When Teasle and his deputies restrain and shave Rambo, he flashes back to his time as a prisoner of war and unleashes his fury on the officers. He narrowly escapes the manhunt, but it will take his former commander (Richard Crenna) to save the hunters from the hunted.
Motorcycle racer Lyle Swann (Fred Ward) is cruising through the Mexican desert when he accidentally stumbles into a time-travel experiment and finds himself transported back to the Old West of the 1870s. There he encounters an attractive local woman (Belinda Bauer) and a gang of criminals led by Porter Reese (Peter Coyote). Lyle’s motorized bike is impressive in the past — until it runs out of gas. Now Lyle must rely on his wits to take care of business and return to his own time.
