Dr. Harrison and Prof. Nordstrom develop the robot Tobor for space flight, intending that he should be controlled by ESP. They announce their plans at a press conference which will spread the news worldwide, then they become concerned that press conference security was breached because an extra person attended and they wouldn't want the information falling into the wrong hands! The extra person was a spy; he and his henchmen kidnap Nordstrom and his grandson, but Nordstrom cleverly signals Tobor to charge to the rescue. The spies tear open the boy's shirt and threaten to use a blowtorch on him, and the composition makes the torch appear to be pointed at the boy's temple while he concentrates on summoning his hero Tobor (the boy's father has been dead for several years, but it looks like Harrison is striking up a relationship with his mother).
