Synopsis.
Actress Elsie Manning (Lora Baxter) is engaged to Horace Baker (Blaine Cordner), but has also been in a romantic relationship with James Nichols (Russell Hicks) who has named her as the beneficiary in his will. Not knowing about her engagement, Nichols asks his wife for a divorce and is refused. Nichols dies in Manning's apartment after she tells him she's engaged to Baker. When Baker arrives on the scene, he agrees to help her dispose of the body by having Nichols moved to a sanitarium. The owner, Dr. Gruelle (Leo Carrillo), tells them Nichols was murdered by poison and attempts to extort money from Manning for his statement that the death was of natural causes. Gruelle tries the same scam on the widow of Nichols (Louise Prussing), who eventually agrees when the poison is found in her purse. It is revealed that Gruelle is really a police inspector named Mr. Maitland intent on solving the murder.
