Blanca Ferrando is a young woman who became blind at the age of twelve, due to a dramatic fire in which her older sister Beatrice died and which was caused by her violent boyfriend, Sebastian. This tragedy made her develop a very strong sense of justice to the point of pushing her to join the police. Blanca is helped by her most trusted friends: her guide dog Linneo, a female bulldog who protects and comforts her in the most difficult moments, and her beautician friend, Stella. After overcoming her work challenges, she finds herself facing sentimental ones: torn between two men, Inspector Michele Liguori, a man of many secrets, and Nanni, a young cook.
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.
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.
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.
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 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.
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.
Blanca is now officially a police consultant while Sebastiano is in prison awaiting trial. Meanwhile, a serial attacker targets the San Teodoro police station.
Bacigalupo investigates a dog fighting ring. Blanca deals with some personal issues: Liguori is jealous of Sebastiano, while she can't stand Veronica, Liguori's childhood friend.
Blanca's sentimental skirmishes with Liguori continue, while he deals with a murder that occurred at the stadium. Meanwhile, Polibomber returns to threaten the police station.
The bomber's case is officially open. Blanca is divided between this case and that of a murder involving a blind girl. Meanwhile, Liguori gets closer again to Blanca.
The team is busy with the attack on a man of Middle Eastern origins while Sebastiano is at the center of the investigation into the attacker. Meanwhile Liguori is torn between Veronica and Blanca.
