A new case reunites the paths of Vanina and Manfredi. It was the doctor, in fact, who saw two suspicious men as they threw a heavy suitcase into the sea, soaked in blood, so Vanina will find herself investigating the murder of a girl that took place in a villa. The victim is the lawyer Lorenza Iannino of whom no other traces can be found. The villa turns out to be owned by the lawyer Elvio Ussaro, a murky prince of the bar, but a macabre discovery will overturn the course of the investigation. Meanwhile, just when Vanina opens her heart to Manfredi, a family commitment puts her face to face again with Paolo and with the unresolved of their relationship.
