A group of college students exploring an abandoned furniture store accidentally discover a hidden basement doorway leading to a bizarre alternate dimension known as the Backrooms. Trapped within an endless maze of yellow corridors, empty offices, forgotten hallways, and impossible spaces, they desperately search for a way home. As supplies dwindle and paranoia grows, the students encounter strange VHS recordings, evidence of a secret organization known as Async, and a lone survivor who claims the Backrooms are far older and more dangerous than anyone realizes. Meanwhile, a terrifying entity stalks the labyrinth, forcing the group deeper into unexplored levels where the laws of reality no longer apply. To escape, they must uncover the truth behind the abandoned store, Async's experiments, and the dark force that may have created the Backrooms itself.
