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.

The town of Newnan are seeing little green men everywhere. The military have arrived and are on the lookout for UFOs. Everyone's high strung and Sheriff Hall (Bud Spencer) is left to deal with the aftermaths of the hysteria. On his way home from patrol he happens upon a little boy claiming to be an alien by the name of H7-25. At first the sheriff doesn't believe the boy, but with the mounting evidence, even he must eventually concede. Soon the military is after Sheriff Hall and H7-25, and it is up to the sheriff to keep the boy safe and beat up large swaths of soldiers so H7-25 can go home.

On his way back from the Civil War, Johnny Hamilton is visited in his sleep by the ghost of his father who lets him know that he has been murdered and who asks him to avenge him. Back in the family ranch, Johnny finds that not only has his father been killed but that Gertrude, his mother, has married her late husband's brother Claude. The latter is now the owner of the ranch and of all the properties of the deceased. Polonius, a ruthless bandit, is supposed to have killed Johnny's father. But couldn't it be Claude...?
