Married socialite Claudette Colbert wakes up on a Boston-bound train with no memory of doing so. Returning home to New York and worried husband Don Ameche, she begins to exhibit signs of increasingly eccentric─and dangerous─behavior, prompting smitten acquaintance Robert Cummings to investigate. Is Colbert going insane, or is something more sinister at work? Director Douglas Sirk's intriguing, noirish thriller also stars Raymond Burr, George Coulouris, Rita Johnson. 97 min. Standard; Soundtrack: English.
