A nine-year-old boy learns to have a greater appreciation for his mother when she is kidnapped by Martians. The alien race decide to take her away so that they can use her maternal instincts to rear their young, but the boy stows away on their spaceship so that he can bring her back to Earth, befriending a subterranean-dwelling Earthling and a Martian along the way.
