Backrooms: Reminiscence | movie | 2026 | Official Teaser

William finally accepts his father’s offer to work on a mysterious project within his company. But what begins as a reluctant attempt to reconnect with his father soon becomes something far more sinister. At the center of the project is an experimental inter-dimensional portal, a doorway to a place that was never meant to be found. As William ventures deeper into the endless, shifting spaces beyond it, reality begins to fracture around him. Memories blur, time loses meaning, and the line between what is real and what exists only in his mind slowly disappears. With each journey through the portal, William leaves another piece of himself behind. Until eventually, there is no coming back.
