If you've spent years falling down the rabbit hole of Backrooms lore online. Kane Parsons' feature debut delivers exactly what you would hope for - a deeply unsettling trip into liminal horror. For newcomers, however, the experience may feel like wandering through an endless maze without a map.

Based on the viral creepypasta and Parsons' hugely popular YouTube series, Backrooms follows Clark (Chiwetel Ejiofor), a failed architect now running a struggling furniture store called Captain Clark's Ottoman Empire. Recently kicked out by his wife and stuck in a life he never imagined for himself, Clark attends therapy sessions with Dr Mary Kline (Renate Reinsve), who is dealing with emotional baggage of her own. Their conversations about loneliness, memory and feeling trapped become the emotional backbone of the film.
