An 11-year-old becomes attached to the robot (unimaginatively named "Tobor," or robot spelled backwards) invented by his grandfather, Holmes. Most of the plot concerns the relationship between the boy, the inventor, and the robot, which has feelings. Some anticommunist propaganda seeps in
when Holmes and Chapin are captured by Reds. Of course, Tobor manages to rescue them, only to be rewarded with an eternal existence in space. Aimed solely at arousing sentiment.
