In this sumptuous thriller by legendary filmmaker Douglas Sirk and featuring a bevy of classic stars of the silver screen, a serial killer is on the loose in London, luring young women into his web through ads placed in the personal column. Scotland Yard's bait to ensnare the villain is a young American dance hall girl (played by a stunning Lucille Ball), who encounters a series of likely suspects, including the always dashing George Sanders as a sophisticated playboy and an unforgettable Boris Karloff as a mad fashion designer.
