Snaporaz (Marcello Mastroianni) is travelling in a compartment on a train when he lapses into sleep and dreams the ensuing story. He follows a woman off the train and through a field and then loses her. Soon, as a representative of the male sex in general he finds himself in a hotel, among myriad women attending a feminist conference. Surreal episodes take him through a villa with his alter-ego, Dr. Katzone (Ettore Manni) and references to his sexual exploits. Reunited with his former wife for a moment, he starts another sequence which reviews his past.
