It is loosely based on true events from the 1991 Vallecas case where Estefanía Gutiérrez Lázaro died mysteriously after she used a ouija board.

The film opens in 1991 in medias res, with emergency services responding to a call from a young girl. She sounds panicked and screams about something coming to get her brother before the call cuts off. The film goes back in time three days. Verónica is a 15-year-old girl living with her mother and three young siblings in an apartment in the working-class district of Vallecas, Madrid. Verónica and her friends Rosa and Diana go into the basement to conduct a séance using a Ouija board.

Verónica wants to reach out to her late father, and Diana her late boyfriend, who died in a motorcycle accident. Rosa and Diana pull their hands back when the glass cup becomes too hot. Verónica begins experiencing paranormal occurrences and her friends avoid her. Looking for answers, she goes back to the school basement and finds the school’s elderly blind nun whom the students call “Sister Death. The nun explains that the séance attached a dark spirit to her and tries to compel the spirit to leave, but nothing happens.

Verónica draws protective Viking symbols for the kids, only for the demon to destroy them. She tries to help Lucia when the spirit chokes her, but Lucia says it was Verónica who was choking her. Verónica wakes up to find that she’s on her first period. As she scrubs her mattress, she finds burn marks on the underside. Desperate, Verónica decides to hold the séance with her siblings. She has Antoñito draw the protective symbols on the walls, but he flips to the wrong page and instead draws symbols of invocation. When she tells the spirit to say goodbye, it refuses.

She calls the police and escapes with her siblings. However, she sees that she is not actually holding Antoñito but had imagined it. Her brother is actually hiding in a closet. She finds him but he won’t go with her. Five years later in 1996, he reports of unexplained paranormal activity having occurred in Madrid.
