Ever stood in an empty corridor which seems to stretch on forever, or found yourself in a deserted room that feels "off"?

Chances are you have encountered these spaces of transition like a hotel hallway, an airport gate, or a Severance-style office corridor which seems simultaneously familiar and eerie. It’s as if time were suspended in a place neither alienating enough to be considered horrific, but not ordinary enough to be reassuring.

But have you ever “noclipped” out of reality and found yourself in a never-ending drab interior where evil make lurk around the corner? Let’s hope not.

This is the plight facing failed architect and depressed furniture store owner Clark (Chiwetel Ejiofor), the lead protagonist in 20-year-old YouTuber and now first-time director Kane Parsons’ Backrooms. He finds an invisible portal inside Cap’n Clark’s Ottoman Empire, which leads him to an extradimensional space with jaundiced walls, humming lights, and endless levels.

When Clark disappears inside this banal yet bizarre maze of liminal spaces, his therapist Mary (Renate Reinsve) goes searching for him and ends up going through the looking glass... She too will discover that Wonderland, this ain’t.
