Our men are investigating a trafficking in Nazi artifacts that would be headed by Lorenzo, a former drug dealer who now runs the diving center of his girlfriend's family. But can a man really change his life? This question is also asked by Blanca, trying to understand what she feels for Liguori, who is increasingly elusive, and for Nanni. Meanwhile, unbeknownst to her, someone sneaks in to spy on her in the same house as hers.

The case that Blanca finds herself investigating interests her very closely: it concerns Carmine Russo, the father of Sebastiano, the boy she had indicated as her sister's murderer. The girl's health is increasingly compromised, while without knowing it she is inexorably approaching a dangerous trap that has been waiting for her for some time now.
