Jim Craig has lived his first 18 years in the mountains of Australia on his father’s farm. The death of his father forces him to go to the low lands to earn enough money to get the farm back on its feet. Kirk Douglas plays two roles as twin brothers who haven’t spoken for years, one of whom was Jim’s father’s best friend and the other of whom is the father of the girl he wants to marry.

Dr. Bill Cortner (Jason Evers) and his fiancée, Jan Compton (Virginia Leith), are driving to his lab when they get into a horrible car accident. Compton is decapitated. But Cortner is not fazed by this seemingly insurmountable hurdle. His expertise is in transplants, and he is excited to perform the first head transplant. Keeping Compton’s head alive in his lab, Cortner plans the groundbreaking yet unorthodox surgery. First, however, he needs a body.
