Wealthy Mrs. Daniels (
Gloria Swanson) is convinced that Dave Snowden (
James MacArthur), the current boyfriend of her daughter, Bonnie (Lynn Loring), is just another fortune hunter, even though Dave insists upon marrying Bonnie after Mrs. Daniels disinherits her. But when Dave runs out of money, he cooks up a scheme to persuade Mrs. Daniels to loosen the purse strings -- a scheme that involves Bonnie faking suicide. Alas, tragedy ensues, but this is only a prologue to the episode's macabre climax, in which the inquisitive Mr. Snowden finally learns what is "behind the locked door" in the deserted mansion on the Daniels' estate. ~ Hal Erickson, All Movie Guide
