There, she senses strange and terrifying phenomena, an invisible entity that knows her deepest secrets, including an affair with Carlos (Jan Cornet). Trapped in the house by the entity, Marga discovers a portal leading to another reality, where she encounters her alternate self, played by herself, who is trying to prevent a terrible event from occurring.
