them to believe that someone has infiltrated the closely guarded laboratory. Aware that their robot could fall into the wrong hands, they construct a small transmitter in a fountain pen that is able to communicate with Tobor. An organized attack by the foreign agents is thwarted by the defensive devices at the Nordstrom's home, so the spies devise another scheme. Sending Gadge and his grandfather an invitation to a space flight presentation at the Griffith Park Planetarium, they intend to hold them hostage. When Gadge and Nordstrom show up, the spies kidnap them. Dr. Gustav (Peter Brocco) tries to force Nordstrom to provide the crucial information needed to control Tobor. When Nordstrom and Gadge do not return for the military demonstration of Tobor's abilities, Dr. Harrison contacts the local sheriff with his concerns that something dire has happened to them. Tobor is suddenly activated, reacting to messages sent by Nordstrom, and storms out of the house, driving away in a military Jeep. Nordstrom is actually controlling the robot remotely with the pen transmitter, while trying to fool Dr. Gustav. One of the spies realizes that the pen is important and snatches it away, breaking it. Guessing that Tobor is going to rescue the professor and Gadge, Harrison and the military follow. At the agents' lair, when the transmissions stop, Tobor comes to an abrupt halt, but Harrison successfully re-activates the robot using telepathic commands. The spies threaten to hurt Gadge, who instinctively reacts and uses his mind to call out to Tobor. Nordstrom relents, writing out the control formula. With Harrison and the military, the robot breaks down the lair's door and attacks the enemy agents, rescuing the professor and Gadge. When one of the spies attempts to drive away with the coerced information, Tobor yanks him out of his car. Gadge is then gently carried out by the robot. Later, when Tobor has been successfully reprogrammed, a spacecraft is launched with the robot in full control of the mission.
