In 1950 in Australia Aunt Agatha writes to Toto, informing him not to send him in Italy even a penny until he is married. Toto is in fact a great bachelor who dabbles in sculpture and live in luxury with the money of her aunt. Now Toto is threatened and forced to be with a woman just because Aunt would soon come to Rome to meet the new couple. Thanks to a friend (Aroldo Tieri) Toto is helped but the women that gives him are horrible or are already ammogliate, which causes many misunderstandings. At the end bull is mistaken for a delinquent because of mistaken identity and misunderstanding continues when they come into the house of Toto's aunt and the new "wife", or a woman who is made to pay for pretending to be his wife Toto.
