The interrogation of Santos brings to light the mistakes the police made in the Lara Macaya case. Elena then confronts her superior, Rentero, who strips her of the investigation. A search of Vistas's cell uncovers letters sent by a former fellow inmate, Candela, referencing a ritual connected to the murders of both Lara and Susana. Chesca and Orduño, joined by Elena, head to the unsettling squat where he lives, while Zárate pays a visit to Jáuregui — Vistas's lawyer — and questions him about the inconsistencies in his defence strategy at trial.
