The horror film [REC] — directed by Jaume Balagueró and Paco Plaza, and released in 2007 — was an unprecedented triumph for Spanish fantasy cinema. Fifteen years later, those responsible for the creation and worldwide success of this cinematic milestone decode its keys and resurrect the myth.

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

Two lovers in a motel. Suddenly, something that apparently has happened outside makes the place become full of journalists, photographers and police. This situation of locking will increase the tension between the couple. Until it explodes.

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.
