Olga and Horacio, two work colleagues, decide to go out one night and end up having sex in the car in the middle of the forest. The next day they discover that they cannot leave the place, since they are in an area with strange magnetisms because it is controlled by some type of unknown intelligence.

Laura inherits her aunt's house and decides to stay there for a few days with her boyfriend Ricardo to renovate it and sell it. A friend of both, Karina, who recently separated from her boyfriend, asks to stay there for a few days as well. Soon, the three realize that, despite the house having been closed for years, someone (or something) still lives there.
