 In a small seaside town in Italy, Moraldo Rubini (Franco Interlenghi), Alberto (Alberto Sordi), Fausto Moretti (Franco Fabrizi), Leopoldo Vannucci (Leopoldo Trieste) and Riccardo (Riccardo Fellini) form a group of idle friends that spend their time together doing nothing but drinking, flirting and going to parties. When Fausto s girlfriend Sandra Rubini (Eleonora Ruffo) gets pregnant, he is pressed by his own father to marry her. However, the irresponsible Fausto remains unfaithful to Sandra, cheating her with many women and almost leading his family to a tragedy.
