The Ghost in the Invisible Bikini

The ghost of recently dead Mr. Hiram Stokeley (Boris Karloff) finds that he has 24 hours to perform one good deed to get into Heaven. He enlists the help of his long-dead girlfriend, Cecily, to stop his lawyer, Reginald Ripper (Basil Rathbone), and a henchman from claiming the estate for themselves. The real heirs, Chuck, Lili, Hiram's cousin Myrtle, and her son bring their beach party friends to the mansion for a pool party while Reginald Ripper also employs his daughter Sinistra, and J. Sinister Hulk's slow-witted associates Chicken Feather and Yolanda to help them terrorize the teens, while dopey biker Eric Von Zipper and his Malibu Rat Pack bikers also get involved in pursuing Yolanda for a share of the Stokely estate.
