The former Chicago police officers receive a crash course in ancient Hawaiian customs during an island investigation in which "an ancient icon" predicts their doom.

A former partner (Tige Andrews) from Chicago arrives and immediately begins running Mac and Andy's lives during their investigation into an unidentified man's murder.

The arrival of Mac's mother (Shelley Winters) only compounds the troubles for the two detectives who must contend with prostitute Cookie Fondue (Donna Dixon), the sole witness to a murder.
