Living in his palazzo are lost and eccentric souls: Poppi, a lawyer; Luciana and her son; and Luca, a doctor, whose wife Viola holds a secret that could destroy their marriage. Right from the start Pietro has a special interest in Luca and his family, and soon he's letting himself into their apartment while everyone is out.
