"Lula, 'bon vivant' who subsists at the expense of small blows, goes on with his life without a present or future purpose. Basically, he just tries to forget having been abandoned by his fiancee Helena, who gave in to his father's imposition. The situations in which he gets involved from then on are paradoxical, trying to survive in the best possible way and spending money he doesn't have, but which comes to him in one way or another. On a day of complete despair, Lula meets a group of "hippies" and leaves catechized. Willing to anything, he becomes a preacher of new customs and new ethics of life. In turn, Helena, whose marriage had failed, dreams of meeting Lula again, hoping to return to his arms.
