Plot
A young mother of two, Alejandra, is unhappy in her marriage to her husband Ángel, who is in a secret affair with Alejandra's brother, a nurse named Fabian. In public however, Ángel makes fun of Fabian and gays in general. Alejandra is desperately unhappy in her marriage and extremely sexually frustrated. While in the shower, she masturbates and almost reaches an orgasm until her kids knock on the door, interrupting her.
Veronica is a young woman who is sexually infatuated with a tentacled alien creature originating from a crashed meteor that an elderly couple keep in a barn in the countryside. She has been visiting the alien for years, having sexual encounters where the creature brings her to orgasm. Having never injured her in the past, the creature suddenly bites her in the abdomen. At the hospital, she is cared for by Fabian, and makes friends with him. When she tells the older couple she wants to continue visiting the alien, they forbid it, as it has become dangerous for her.
Ángel visits Fabián and angrily demands to know why Fabian has not answered his texts. Fabián informs him that their affair is over. Veronica entices Fabián to visit the barn, but later Fabián is found naked in a field, sexually assaulted and beaten into a coma. As he lies in the hospital, Alejandra finds his phone and reads the angry texts from Ángel, in which Ángel demands sex from him, threatening violence. Ángel is arrested at work, and Alejandra testifies against him, as does one of Fabián's co-workers, who witnessed their disputes.
