Ricciardetto is a fourteenth-century playboy who wants at all costs to sleep with the wife of the mayor of Montelupone. He succeeds, but is caught between the covers with the woman and sentenced to death. He will be saved by a kind of pilgrim saint who is in love with him.
Doña Pura, don Benito and don Augusto are three venerable old people who usually coincide each month in the queues of the mutuality windows to collect their pension, an opportunity they take advantage of to talk about life. When they learn that the old don Felipe, an acquaintance, is very sick and is alone and without money for a decent funeral, they decide to ask for a loan to help him, but, as they do not grant it, they decide to rob the savings bank. To do this, they will plan everything thoroughly and manufacture a homemade explosive.
