The film's theme song "Sheriff", written and performed, like the rest of the soundtrack, by Guido & Maurizio De Angelis (then known as Oliver Onions), was a local airplay hit in the same year.

The only one remaining untouched by this hubbub is Sheriff Hall (Spencer), the big and punchy keeper of the local law; indeed, he does not believe in aliens, especially since layabouts like Brennan (Joe Bugner) use the excitement to commit all sorts of mischief.

Still, the sheriff is not convinced – not until the boy irradiates him with what he calls "bio-magnetic energy", enabling him to make a large trout leap into his hands and a horse talk in English.

Meanwhile, however, an ambitious Air Force Captain named Briggs (Raimund Harmstorf) sees his chance with the UFO sighting and the evidence of an alien landing (which is, of course, H7-25's doing and caused the aforementioned blackout) to further his own career.

Working without the knowledge of his highly sceptical general, Briggs tracks down the boy, but his first attempts to take him are foiled by the sheriff's hard-hitting fists and H7-25's technical wizard device, as well as Brennan's assistance.
