In this Italian comedy from the 1960s, we follow the life of a middle-aged man named Alberto, a journalist living a quiet and monotonous existence. His life changes drastically when he begins to suspect that his young wife, a vivacious and charming woman, is being unfaithful to him. Consumed by jealousy and insecurity, Alberto embarks on a series of hilarious and clumsy attempts to uncover the truth behind his suspicions.
As the plot unfolds, Alberto is surrounded by a comedic duo of friends; one is a stereotypical womanizer who offers him unorthodox advice, while the other is a more sensible man who tries to keep his friend grounded in reality. Alberto's misadventures lead him to comedic and absurd scenarios, ranging from misunderstandings with his wife to humorous encounters with men he suspects to be his rivals.
The tone of the film is light-hearted, filled with witty dialogue and surreal situations that reflect the protagonist's confusion and pathos. In the end, Alberto discovers that his paranoia not only affects his relationship but also leads him to question who he really is. As the story progresses, issues of trust, communication, and what it means to be a "cuckold" are raised. With a fresh and humorous approach, the film offers a subtle critique of the couple dynamics of the time.
