A radio-controlled bomb accurate within 200 miles is the cause of much mayhem in this low-budget science fiction-thriller based on a story by pulp writer Peter B. Kyne. A hayseed prizefighter, Lefty (Fuzzy Knight), and his manager, Red (Syd Saylor), are hired by Dr. Marston (Forrest Taylor) to bodyguard the device but both are knocked unconscious and the secret blueprints are stolen when a tear gas bomb explodes in the laboratory. Assigned to investigate both the blast and the theft, Secret Service Agent Ted Kelly (Lloyd Hughes) discovers that Dr. Walsh (John Elliott), the uncle of Marston's pretty secretary (Sheila Manners), was the real inventor of the bomb, Marston having stolen the formula by using his hypnotic powers. Pretending to fall under Marston's spell, Kelly solves the case and the world is once again safe from Marston and his minions. ~ Hans J. Wollstein, Rovi
