A betrayed wife decides to teach her philandering husband a lesson in this riotous farce. Marta (Catherine Spaak) discovers that husband Franco (Nino Manfredi) has been stepping out with her own best friend (Maria Grazia Buccella), and gets revenge by inventing an imaginary lover. Franco takes the bait, leading to improbable but hilarious complications.
