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.

A vengeful criminal targets the inspector who put him away, but the inspector survives and fakes his death. Ignoring orders to flee, he sets out to bring the fugitive back to justice.

They are attacked by a bandit gang, and only a sergeant, his beautiful young daughter and an assortment of seven sadistic, murderous prisoners survive, and they are left without horses or a wagon. The sergeant must find a way to get his prisoners to their destination while protecting his daughter, watching out for the still pursuing bandits and trying to determine which one of the prisoners was the man who raped and murdered his wife.
