Annibale is an old libertine who has come up with enormous luck with prostitution homes. Now, having long been in danger of death, but little in spirit, he would like to leave all his inheritance to the nephew Andrea, son of Teodoro and Iliana. When he comes to know that Andrea, attracted by the twin brother of Grandfather Nestore who is a bishop, would like to become a priest, the inflexible Annibale will change the will and order the construction of a hospice for the admission of elderly prostitutes.
