Martín arrives in Chantada, a small village in Galicia, with the intention of investigating a paranormal phenomenon that happens every thirty years. An unexpected event leads him to meet Rocío, a Guardia Civil agent. He also meets Abril, a mysterious woman who lives far from the rest of the world.

A female hiker appears at the Guardia Civil police station telling that her boyfriend has disappeared into the forest. The area where both were camped is next to where the corpse of Suso Salgueiro appeared. Rocío begins to suspect Martín, so she goes to the forest to bring him back.

Martín, Rocío and Abril have to join forces. After fainting, Abril tries to explain what happens: she is a meiga and Rocío is a witch. Rocío cannot believe what she's listening to. Contact people from beyond? Any doubt about her powers disappears after their first contact with the Santa Compaña.

Abril helps Rocío to enter the world of the dead. Once there, she sees Abril's son, disappeared thirty years ago. Martín has been lost in the woods. While the witch and the meiga face the Santa Compaña, he will have to defend himself alone. What Rocío cannot get out of her head is that her father is one of the walkers trapped in the procession of the Santa Compaña.

Martín is trapped in the world of the dead and only Rocío can save him. Will Abril be able to contact her to let her know that she has to close the cold spot?
