Mario takes his medication: he's stable and is increasingly closer to his sister. Leo realizes that, for a long time, he's been on the wrong side. Now he always meets with Nico; he's the only one he can vent his anger to: he hates that town and, above all, Aure. Sara prefers to keep her distance from Víctor. She knows he doesn't want to continue at the UCO: the cases he's worked on have ended up burning him out. That's why she requested a transfer to Monteperdido. Rita manages to free Alicia, but the effort leaves her exhausted. Alicia recognizes the area; she's on the old smugglers' route. Her father taught her everything. A few kilometers away, they'll find a town and they'll be able to help them.

We see what happened the night Alicia disappeared. Meanwhile, Víctor searches for Leo. He finds Nico, her boyfriend, and when he asks him about her, the boy looks at him in surprise. Leo? He doesn't know anything about her, he barely knows her. Sara finds La Guardiña.
