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.
