Sasquatch, believed by Steve Austin to have gone back into space with the aliens who created him, is spotted in the wilderness and goes on a rampage. When Steve learns that Bigfoot has been seen and photographed by anthropologist Hope Langston, he goes to her camp to try to persuade her not to capture the cybernetic beast. But the young woman defies him. Steve eventually catches up with his old friend, who inexplicably attacks him, then runs away. Meanwhile, Langston's associates, Jason O'Neal and Charlie Wynn, make plans to catch Bigfoot on their own and make a fortune by exploiting him.
