Plot title: Wait Until Dark Movie plot: The film opens in a Montreal apartment during a cold wintery morning, where a woman named Lisa (Samantha Jones) waits for an old man to sew bags of heroin into the cloth body of an old-fashioned doll. As she leaves the apartment with the doll, we see the man watching her leave, then dialing someone on the phone. Lisa takes the doll with her on an airline flight to New York City, but when, on disembarking, she sees a man watching her, she becomes worried and gives the doll for safekeeping to a man she'd spoken with on the plane, professional photographer Sam Hendrix (Efrem Zimbalist Jr.). The man who'd been watching Lisa then roughly escorts her away. Later, when Lisa calls Sam to ask for the doll, Sam and his wife are unable to find it.Some time afterward, small-time con artist Mike Talman (Richard Crenna) and his partner Carlino (Jack Weston) arrive at the basement apartment where Sam lives with his wife Susy (Audrey Hepburn), who is blind.

Roat is then able to prevail upon the two to help him dispose of Lisa's body (he claims that he killed her because he caught her going into business for herself). Roat firmly tells Talman and Carlino help him try to find the heroin-stuffed doll.The next day, Susy's neighbor leaves for the weekend, and Sam leaves for a business trip to New Jersey. Once Susy is alone, the criminals begin an elaborate con game: In order to gain... My question: Who calls Roat at the phone booth?
