A mysterious man known as the Gemini seeks to launder $ 4 million. Jack Cole and Hector Ramirez try to unravel his identity in order to prevent the operation. They are assisted by Angie Parker, charming stewardess who was left unintentionally embroiled in this case because of Victor Radick, a blackmailer.

Jack tees off on the mob when he poses as a golf pro to help a federal judge who is in debt to the syndicate—and happens to be presiding over an important crime czar's homicide trial.
