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 journey of years through many countries and film festivals; a nostalgic, adrenaline-fueled and rock-spirited immersion into the universe of cinephilia, in search of genre specialists, fans and filmmakers who speak of their shared passion for fantastic cinema; a whole international spiritual community united under the cathartic shadow of horror.

The story of the making and subsequent success of The Day of the Beast, the Spanish cult film directed by Álex de la Iglesia and released in 1995.
