In this farcical comedy of errors, Marcello (Renzo Montagnani), a man devoted to his glorious single life, finds out that he can only receive an inheritance from his mother if he marries - and that is just out of the question. Meanwhile, he must somehow make his father - now a bishop living in Brazil - believe that he plans to soon tie the knot. That is where Amelia (Barbara Bouchet) enters the picture. As Marcello works on his deception, many loopy characters weave in and out of the story: Amelia's brother who loves to wear any great costumes he can find, a gardener obsessed by the subject of bombs, an Arab sheik, and other unlikely figures. Meanwhile, Amelia's real boyfriend Stefano (Gianni Cavina) is always a force that cannot be ignored.
