Kelly, who was orphaned as an infant, receives a visit from attorney Bill Cord, who is convinced that she's Margaret Barrows, the daughter of multi-millionaire hotelier Oliver Barrows. Kelly flies to San Diego to meet the man who may be her father, and begins a romance with the handsome attorney. After a joyful reunion, Barrows dies of an apparent heart attack two days later.

What Kelly does not know is that Oliver was poisoned by his nephew, Glenn Staley. Deep in debt, Staley promised to deluver Barrows' San Diego hotel to a developer with syndicate ties. Hoping the murder of Oliver would solve the problem, Glenn is now faced with the necessity of killing the new heiress. Kelly, meanwhile, is still uncertain about her real heritage, and hires Kris, Tiffany and Bosley to find proof. Tiffany joins Kelly in San Diego to study the Barrows family history, while Kris follows up on Bill Cord's investigation. In the course of their collaboration, Bill and Kris fall in love!
