Cathedrals

In an empty lot in Ñuñoa, a residential district of Santiago, Chile, the body of Ana Sardá is found. She is a 17-year-old girl raised in a deeply Catholic family. The crime shocks the neighbourhood and the case is marred by irregularities from the very beginning. The case is assigned to Elmer García Bellomo, a young criminal investigator facing his first major professional challenge.

Lía tracks down Elmer, the investigator who handled the case 30 years earlier. She finds that he's become a writer and an independent investigator, completely jaded by the system and the police force that closed her sister's case without answers.

Lía, Alfredo and Mateo meet with Marcela at San Gabriel Church, as Marcela insists it is the same place where Ana's tragedy took place 30 years earlier. There, Lía confronts her with a suspicion she can no longer keep silent.

During the parish youth camp, Ana goes through days of apparent enthusiasm that conceal a deep loneliness. Away from her usual surroundings, she finds refuge in drawing and in the silent observation of those around her.

Following Alfredo's death, Lía discovers a letter from her father that reveals who Ana's secret lover was; as the truth comes to light, the past resurfaces; Carmen breaks down at the revelation and a discovery in the family oven confirms unthinkable.

Ana goes through a time of great fragility, surrounded by adults who, guided by their own religious and moral convictions, believe they know what is best for her; Carmen reinforces her role as the guardian of the family order.
