Hired by Dr. Philip Stark (Donald Murphy) to care for his invalid wife Frances, college coed Betty Kaster (Margaret Bly) goes to Perry Mason (Raymond Burr) with her suspicions that Stark plans to murder Frances for her $2,000,000 inheritance. A murder does indeed take place, but it's Stark who is killed and it's Betty who is charged with the crime. In mounting Betty's defense, Perry must wade through a veritable Tsunami of greedy relatives, and must also contend with the victim's not-so-secret girlfriend Jill Fenwick (Joan O'Brian). And there's another complication: Is the "helpless" Frances Stark really all she claims to be?
