Sleep, My Love is a 1948 black-and-white film noir directed by Douglas Sirk. When Alison Courtland (Claudette Colbert) awakens at midnight on a train headed towards Boston, she can't remember any details about how she got there. The last thing that the wealthy New Yorker remembers is going to bed with her husband in her own home. She phones her husband Richard (Don Ameche), who tells Alison that she fired a shot at him the previous night. Alison does indeed find a gun in her bag, but she does not have any idea why she would have tried to shoot Richard. When Alison returns home, her husband makes her see Dr. Rhinehart (Ralph Morgan), a psychiatrist who just seems to be making her go more crazy and have additional memory lapses. With the help of Bruce Elcott (Robert Cummings), a new friend that she met on her flight home, Alison must struggle to uncover the reason behind her new madness.
