It's 1348. The plague has brutally hit Florence. A group of then young people, seven women and three men, rebel against the feeling of death that is about to swallow them. They flee the city and find refuge in an abandoned villa in the Tuscan hills. Here, between moral doubts and the tasks needed to survive, they kill time by telling each other stories until they will decide to return. The stories are varied - tragic, bizarre, funny or erotic - but common and central to all of them is the female presence.

Pietro is a revered teacher, Teresa his brilliant and precocious student. Their affair is both illicit and tempestuous. After one fight, Teresa suggests that each tell the other a secret, one so shameful or shocking that were it to be made public, it would destroy that person’s life. Time passes, Pietro’s stature as a writer grows and his family settles into the comfort of a bourgeois life. But he is haunted by the possibility that Teresa may one day reappear and tear apart his world with the secret she knows.
