Minor but not unintelligent British sci-? thriller (from a novel by Frank Crisp) with imported star Saxon looking as though he hasn't quite found his bearings yet. The plot involves a UFO (an energy valve for transmuting matter), a female scientist (Haines, persuasive) who succumbs at the close to chief alien Medra (Crewdson), and sundry young women who answer the advertisements of Medra's modelling agency, only to be spirited away to planet Ganymede for genetic jiggery-pokery.
