A dull German thriller with elements of science fiction woven into its femme fatale storyline. Hildegard Knef is the test-tube spawn of a prostitute and executed killer created by an ageing Erich von Stroheim who apparently has the power to beguile every man she meets. A young Karlheinz Bohm plays the young hero who fights his desire for her without passion or conviction - although, to be fair, the pedestrian script gives him little to work with.
