A loving young husband (popular Italian comedian Antonio Albanese) goes out one night to get his pregnant wife Beatrice (Valeria Milillo) the jar of mushrooms she craves and does not return for five years. Unbeknownst to either of them, Antonio was about to buy the mushrooms when a large package fell and conked him on the head. He regained consciousness with no memory whatsoever and simply wandered away. Five years later, he returns home with his wife's mushrooms with no idea that he had lost his memory. Unfortunately, by this time Beatrice has taken up with Gotffredo (Antonio Petrocelli), an experimental musician. He is the only father, her daughter Tonina (Sara Anticoli) knows. Undeterred, Antonio launches a determined, comical campaign to win back the naturally reticent Beatrice.
