Beyond a door that should not exist beckons an infinite series of rooms and hallways, at once familiar and eerily foreboding. What will you find in the Backrooms – and what will find you?

From the mind of visionary YouTube creator Kane Parsons, making his feature-filmmaking debut, comes a dread-inducing cinematic nightmare, poised to define a new era in horror storytelling – releasing regionally on 28 May.

Set in 1990 and based on Parsons’ viral web series, BACKROOMS follows furniture salesman Clark (Chiwetel Ejiofor) as he makes a startling discovery in the basement of his showroom — a portal, bathed in yellow fluorescent lights and littered with familiar objects, leading to an eerie maze of endless office space.

Shaken by what he discovers there, Clark is also drawn to its anomalies. He enlists his skeptical employee Kat (Lukita Maxwell) and her boyfriend Bobby (Finn Bennett) to help chart its unsettling expanse of impossibly constructed rooms and corridors, where strange noises hint that something otherworldly may be lurking in the shadows.

When Clark goes missing, his therapist Dr. Mary Kline (Renate Reinsve), confronting buried traumas of her own, finds herself lost in the BACKROOMS searching for answers, and a way out.

Directed by Parsons from a script by Will Soodik (WESTWORLD) based on the series by Parsons, BACKROOMS stars Academy Award®-nominee Chiwetel Ejiofor (12 YEARS A SLAVE) and Academy Award®-nominee Renate Reinsve (SENTIMENTAL VALUE) in a groundbreaking expansion of the viral BACKROOMS world.

Filmed predominantly on real sets, it unveils previously unknown dimensions to Parsons’ chilling universe and brings the CG found-footage series into the live-action realm, announcing the arrival of a singular new voice in horror cinema.
