A young humanoid alien who gets stranded on earth hooks up with a grizzled old sheriff in a western town and tries to help him solve a tough case, but the sheriff doesn't want any help from a "kid."

Following the events of The Sheriff and the Satellite Kid, Sheriff Hall and H-725 (using the official identity of Charlie Warren) still get no rest from the military - because the little alien has not yet grasped the meaning of keeping a low profile. They are constantly on the move, and H-725's father has had to pick them out of a tight spot too many times already.
