In this comedy of errors from Italy, Stefano (Luca Bizzarri) is a 30-year-old businessman with a wife, a child, and a lot of second thoughts about the direction that his life has taken. One day, Stefano discovers that his bank has made an error in his favor, and 6 billion lire have ended up in his bank account. Suddenly wealthy, Stefano uses the money to keep his wife Lisa (Luciana Littizzetto) happy with a variety of expensive gifts; he tells her that he's being sent away on business, when he's actually headed to Bologna, where he grew up, and where he now enjoys nostalgic reveries reliving the pleasures of his youth. Stefano also finds some romance on the side with Bolognese beauty Antonia (Maddalena Maggi), who believes Stefano's story that he's an immigrant from Albania. However, Antonia pressures Stefano into getting married, and he finds it's a full time job keeping both Lisa and Antonia happy while making sure they don't know of the other's existence. Director Lucio Pellegrini, screenwriter Fabio Bonifacci, and much of the cast of E Allora Mambo first gained popularity in Italy for their work on the popular television comedy series Ciro.
