The Earthlings witness a giant who goes berserk, trashes a drug store, and murders a security guard with one strike with his bare hand. They learn the man is really a malfunctioning android, created by a scientist named Gorn, who manages to capture Mark and Fitzhugh. When Gorn learns Mark is an engineer, he makes a deal with him to figure out what is wrong with his robot in exchange for his freedom. Mark gets the machine working, but when Gorn is not forthcoming with his end of the deal, Steve and the others climb inside the robot and hi-jack it.
