Set in Berlin, a military doctor (Van Johnson) is suspected of drug peddling and murder. He escapes from the military police and sneaks into his wife's (Katherine Kath) apartment since she is the only one who can prove his innocence. Instead, he finds his wife gone and a nightclub chanteuse (Hildegard Knef) living there instead. Based on the play by Ian Main by way of the novel by Bruce Birch and directed by Muriel Box (RATTLE OF A SIMPLE MAN). For a rather stage bound thriller, the majority of the film takes place in a penthouse apartment, this is pleasantly entertaining. It's rather easy to identify the real killer and most of the suspense comes from whether the police will catch an innocent man before he can prove his innocence. The real murderer is a real twisted piece of work and there's one last shocking killing. All in all, a pedestrian piece of film making but who says it has to be great to be enjoyable? Johnson is serviceable but it's Knef who takes over the film and she even gets to sing! With Cec Linder, Vivian Matalon, Albert Lieven and Edward Judd.
