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.
