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.

The disappearance of a young engineering PhD student reopens an unfinished business in Liguori's past. The main suspect, in fact, is the powerful oilman Piccardo, whose lawyer is Livia, Liguori's mother. The case will inevitably bring to light the conflicted relationship between the two, while an unaware Blanca is increasingly in danger at the hands of someone who now controls her and wants to hurt her.

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.

Just when Blanca tries to convince herself that she doesn't care about Liguori, having discovered his relationship with the journalist Marinella, her son disappears. Commissioner Bacigalupo considers a voluntary departure, but Blanca discovers that little Gabriele has been kidnapped. Blanca collaborates in the investigation by listening to the kidnappers' interceptions, but she feels ready to make a difference also on the field, not just behind the scenes. However, choosing her will have serious consequences for her.

The body of sixteen-year-old Camillo is found in an ancient noble palace. The case closely affects Liguori, Blanca's charming colleague: the building belongs to her family and there are painful memories for him. The suspect is Liguori's uncle: Blanca seeks the truth, while she tries to stay close to Lucia and is divided between Liguori and Nanni, her friend and chef. Meanwhile, from the past, someone returns to question his credibility.

The Genoese police station of San Teodoro is turned upside down by the arrival of Blanca, a young blind woman who can finally realize the dream she has cultivated since she was a child: to become a police consultant. Blanca at first collides with everyone's distrust, but she soon demonstrates that she can make an original contribution to the investigation starting with the case of Margherita, a woman found dead under the former Morandi bridge under mysterious circumstances. While she begins to establish a relationship with Lucia, the twelve-year-old daughter of the victim, Blanca brings into play her ability to compensate with the other senses and an incredible intuition for the lack of vision and her "superpowers" prove invaluable in the investigation of the case.
