A Paris model must return to Madrid where her grandmother, who raised her, has had a stroke. But spending just a few days with this relative turns into an unexpected nightmare.

Mario, an exemplary man, lives in a village on the Galician coast. In the old people’s home, where he works as a nurse, everyone appreciates him. When the best known narco in the area, Antonio Padín, recently released from prison, enters the residence, Mario tries to make Antonio feel at home.
Now, Padín´s two sons, Kike and Toño, are in charge of the family business. The failure of an operation will put Kike in jail and cause them to owe a large debt to a Colombian supplier. Toño will turn to the nurse to try to convince his father to assume the debt. But Mario has his own plans.

A television reporter and cameraman follow emergency workers into a dark apartment building and are quickly locked inside with something terrifying.

The action now takes place miles away from the original location and partly in broad daylight, giving the film an entirely fresh yet disturbing new reality. The infection has left the building. In a clever twist that draws together the plots of the first two movies, this third part of the saga also works as a decoder to uncover information hidden in the first two films and leaves the door open for the final installment, the future ‘[REC] 4 Apocalypse.’

The action continues from [REC], with the medical officer and a SWAT team outfitted with video cameras are sent into the sealed off apartment to control the situation.

Madrid, 1990s. After making a Ouija with friends, a teenager is besieged by dangerous supernatural presences that threaten to harm her whole family. Inspired by terrifying police files never solved.
