This children's sci-fi adventure chronicles the friendship between an 11-year-old and his grandfather's robot Tobor, who was designed to explore deep space. Tobor, unlike other machines, was endowed with human emotions. Trouble erupts when the communists kidnap him and try to make him do their evil bidding. Fortunately, Tobor is mind-linked to his creator and cannot be easily reprogrammed. The adventure begins when the boy and the scientists attempt to save the robot.
