Argentina, 2001. The country is in the middle of a state of siege. Bruno leads a rural military patrol of five soldiers into the countryside. They come upon an old farmhouse and inside they find several corpses and two survivors. Unwittingly, they awaken a diabolical entity living in the forest that revives the dead in the house and will torment them all night long. They will have to resist until dawn, or become part of a bloody sacrifice made centuries ago.
