The story turns about an experimental aviator and a cryogenicist, who are flying over Siberia when forced to land, after an airplane mechanical failure. They survive the landing, and happen to find the body of a caveman, frozen into a newly uncovered glacier wall. Jokingly, the aviator suggests that the cryogenicist attempt to revive the man, which he proceeds to do, using transfusions and injections of drugs. The caveman proves to be intelligent, and immensely strong. His name is Kolani and he soon learns enough English to communicate. Returned to America, he is given the stage name of Jim Stone, after he proves to be a professional wrestling sensation who throws all contenders over the ropes, and into the crowd.
