Ramos continues to make Sara's life a living hell, depicting her as a vengeful and unfaithful woman who has unfairly accused a heroic firefighter of these heinous crimes.
A sudden twist sees the chief suspect in the recent spate of killings, firefighter Marc Ramos, being hailed as a hero for saving a woman's life. Meanwhile, Lluís and Clara fly to Tangiers on a business trip together.

Sara comes into possession of an incriminating video of Ramos torturing a prisoner in Iraq and takes the footage first to Ramos' mother in an attempt to make her realize what kind of monster she is protecting.
