"Dark Building" is an old apartment where the rent plummeted after a fatal incident but there are always strange tenants. Xu Chen moved in by mistake and met various alternative co-tenants. Strange things happen frequently in the middle of the night: ghost noises in the corridors, strange phenomena in the cafeteria, elevator dimensionality reduction, nightmare series... As the strange events continue to escalate, several tenants are forced to join forces and repeatedly avert danger in absurd and even funny ways, but the "nightmare" of the black building has not stopped. Every time a layer of mystery is solved, greater truths and crises are ushered in - here, reality and illusion are intertwined, and the supernatural and science collide. They must find self-salvation and belonging to each other in the horror and absurdity. In the end, when the secret emerges, everyone's fate faces a final showdown that is both humorous and terrifying.
