Discover the mystery hiding in the valley.
Amaia Salazar, a police inspector in Pamplona, is directed by her superior to investigate a murder. The case concerns a teenage girl whose naked body was found at the side of a river close to Elizondo, Amaia’s birth town, a rainy village surrounded by forests and mounts, full of local myths and ancient superstitions. Her marriage to James, an American sculptor, is falling apart due to her desire for a child, and despite wishing to never return to her family home, Amaia Salazar is forced to face the past and reconnect with her Aunt Engrasi and her sisters Flora and Rosaura. It seems that Amaia’s instinct for criminal cases will be challenged, as more naked bodies of teenage girls are found in the forest. Trying to solve the case and discover the identity of the killer, Amaia must not only confront her own childhood trauma from the abuses of her mother, but also a growing suspicion that perhaps the killer is someone who is too close for comfort.
