The San Teodoro police station in Genoa is turned upside down by the arrival of Blanca, the new intern with blindness and incredible intuition.

Just when Blanca tries to convince herself that she doesn't care about Liguori, having discovered his relationship with journalist Marinella, her son disappears.

The police investigate a traffic of Nazi relics that would be headed by Lorenzo, a former drug dealer who now runs the diving center of his girlfriend's family.

The disappearance of a young doctoral student in engineering reopens a loose end in Liguori's past and brings to the surface his conflicted relationship with his mother.

The new case Blanca is investigating interests her closely: it concerns Carmine Russo, the father of the boy she had indicated as her sister's murderer.
