With his son Pablo's kidnapping still unsolved, and his marriage ruined by the torment of hope, the brutal murder of a single mother in her own home is an almost welcome diversion for Commandant Vilar.

The woman leaves behind a son, Victor, thrown into the foster system with only his mother's urn for company. Struggling with bullies, trauma and the first pangs of teenage love, Victor carries a secret that followed his mother to her grave.

Struggling for leads, Vilar is shaken when the colleague investigating Pablo's kidnapping disappears. When a sadistic caller claims to have information about his son, Vilar is torn between duty and a desperate chance of redemption.
