synopsis
All the experts have declared that it is impossible to rob a safety-deposit vault surrounded by a sophisticated, high-tech alarm system--but that's just what happens. Clearly the heist was the work of a well-trained team, and the cops are able to arrest one of the suspects almost immediately. Chief Ironside (Raymond Burr), however, is certain that the man in custody is innocent...and meanwhile, the actual master thief is working on a plan to seal Ironside's doom!
