The Civil Guard arrests the first suspect in the case, and this is not well received in Monteperdido. The officers are getting closer to the truth, but the townspeople are uncomfortable with the investigation, feeling treated as if everyone were a suspect. They let Corporal Víctor Gamero know this, and he eventually confronts Sergeant Sara Campos. Meanwhile, Ana tries to return to "normal life." This is not easy. Her return has been a bombshell, resurfacing old secrets that will put the lives of some Monteperdido residents at risk.

Sergeant Sara Campos tries to overcome this and finds a clue that brings her a little closer to Lucía. Ana begins to lose her fear and begin to trust Quim. The facts become increasingly clear: the kidnapper lives among the residents of Monteperdido.
