This movie is the first of a trilogy that Sebastián D'Arbó, a specialist in parapsychology, filmed on occult topics. The second film is El ser (1982) and the last one Más allá de la muerte (1986).

The film makes a home in your brain and the only cure is to see it again.
Story: It's very simple but honestly that is fine.
