Overview
Phantom Lady is a 1944 American film noir directed by Robert Siodmak and starring Franchot Tone, Ella Raines, and Alan Curtis. Based on the novel of the same name by Cornell Woolrich, it follows a young Manhattan secretary and her endeavors to prove that her boss did not murder his wife.
Plot
After a fight with his wife on their anniversary, Scott Henderson, a 32-year-old engineer, picks up an equally unhappy woman at Anselmo's Bar in Manhattan and they take a taxi to see a stage show. The woman refuses to tell him anything about herself. The star of the show they are watching, Estela Monteiro, becomes furious when she notices that she and the mystery woman are wearing the same unusual hat. When Henderson returns home, he finds Police Inspector Burgess and two of his men waiting to question him; his wife has been strangled with one of his neckties. Henderson has a solid alibi, but the bartender, taxi driver, and Monteiro deny seeing the phantom lady. Henderson cannot even clearly describe the woman. He is tried, convicted, and sentenced to death.
Carol Richman, Henderson's loyal secretary, who is secretly in love with him, sets out to prove his innocence. She starts with the bartender. She sits in the bar night after night, staring at and unnerving him. Finally, she follows him home one night. When he confronts her on the street, some bystanders step in to restrain him. He breaks free, runs into the street and is run over. Later, Burgess offers to help (unofficially). He has become convinced that only a fool or an innocent man would have stuck to such a weak alibi. Burgess provides her with information about the drummer at the show, Cliff, who had tried to make eye contact with the mystery lady.
Carol dresses provocatively and goes to another of Cliff's shows, hoping to glean more information. By making intense eye contact with Cliff during the performance, she manages to capture his attention. Afterward, Cliff approaches her, and she returns to his apartment with him. Somewhat drunk, Cliff brags that he was paid $500 for his false testimony. However, he becomes suspicious when he accidentally knocks over her purse and, among the spilled contents, finds a piece of paper with details about him. Richman manages to escape, leaving her purse behind. After she has gone, the real murderer, Henderson's best friend Jack Marlow, shows up at the apartment and strangles Cliff to death.
