Count d'Alsay (Ernst Stankovski) and Col. Delaroche (Sieghardt Rupp) are in a bind. Each inhabits one side of a massive castle, and each claims to own the whole thing. They settle the dispute with a simple wager: whoever first sleeps with the innocent new maid wins the land. But in the steamy heat of competition, Delaroche neglects his fiancée (Edwige Fenech), who promptly pursues another man in this breezy European sex farce.
