Andrés and Ana, an urban couple who live in Madrid, leave their apartment to spend a day of pleasure in the city with their dog. They end up accepting the invitation of two strangers, Bruno and Berta, to go to eat at their country house. A storm surprises them and they have to stay overnight together. The two couples start a session with an Ouija board. Conflicting past situations arise, such as Ana's affair with Andrés's brother or a suicide attempt by Bruno, who receives criticism from Berta. This will be the beginning of the horrors that will take place in the haunted house.—Wiki
