Cabinet member Baron Von Kreitz hatches a plot to overthrow the General Secretary of the United Planets. The Baron sends Lt. Groat to prevent Commander Corry from delivering a report on Venus to the General Secretary. The information is passed to the Assistant Security Chief Tonga, who is wounded and partially paralyzed and imprisoned in the aft compartment of her space car. She manages to activate the ship's magnetizer, leaving a cosmic static trail. This signal allows Commander Corry and Cadet Happy to track her space car to the Baron's hideout on Earth's moon.
