During the school assembly, the principal surprises the students by revealing his rebellious past and ultimately decides to withdraw the controversial circular. Meanwhile, Anna faces a delicate moment in her life and receives an unexpected dinner invitation.

The discovery of the body of an unidentified man, called "Quantunque," sets off a complex investigation full of questions. While the police search for new leads, Anna faces the pain of loss and the desire to know the truth about the victim and his tragic fate.

A new lead emerges in the investigation into Flora's death: Her will reveals the existence of a son given up for adoption many years earlier, the sole heir to her estate. Camilla's husband, Renzo, hasn't come home, and Livietta is concerned. Anna is at the restaurant with Giuseppe, who really seems to want to cook her dinner at his place.

Renzo tries to reconnect with work contacts when Camilla arrives to try to make peace with him. A phone call from the bank interrupts their confrontation, however, and turns the day's plans upside down.
