was adapted from Paul W. Fairman's short story . Set in, of all places, Chicago, this sci-fier concentrates on four people who've congregated in the deserted city after a sudden and mysterious evacuation. The ill-matched foursome are Vicki Harris (Virginia Grey), a flashy, trashy blonde; Nora King (Kathleen Crowley), a young widow; Frank Brooks (Richard Denning), a handsome fellow with a questionable past; and Jim Wilson (Dick Reeves), a brutish transient. Though they don't get along at first, the four strangers are compelled to unite against a common enemy: an invading Venusian army, using huge robots to do their dirty work. Nothing spectacular, works well within its modest limitations.
