The "maguffin" in this Universal melodrama is a revolutionary new swimming vest, created by one Dr. Langtry. Preparing to test out the invention one evening, the doctor passes the home of his nephew, whose wife is currently carrying on with another man. Not wishing to be caught in the act, the wife's lover tries to kill Langtry by drowning him in a nearby river, but the doctor is saved by his miracle vest. He returns to the scene of the crime, where he captures the would-be murderer -- who, in order to justify the film's title, is actually the head of a gang of international criminals. The presence of a secret invention enabled Universal to advertise this nonsensical film as an espionage drama.
