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.
