Hotel waitress Thelma Tompkins (Olive Deering) is surprised to learn that wealthy Mrs. Mannerheim (Celia Lovsky) has named Thelma in her will. Relating this news to her lazy musician boyfriend, Arthur (Rick Jason), in hopes that he will propose to her, Thelma is disappointed when Arthur replies that marriage is out of the question until Mrs. Mannerheim dies. Giving this set of circumstances, Thelma and Arthur have no alternative than to "help" Mrs. Mannerheim shuffle off her mortal coil -- a scheme ultimately foiled by the usual ironic twist. ~ Hal Erickson, Rovi
