All that remains are its dilapidated buildings and dust-covered memories. Yet it has become a breeding ground for terror, with countless bizarre legends circulating about it. Li, a young and courageous police officer, receives what seems like an ordinary patrol assignment, never imagining that it will be the beginning of a nightmare. As he enters the hospital, darkness closes around him like something solid. The floor creaks eerily beneath his feet, as if warning him to stay away. An oppressive feeling hangs in the air, so suffocating that every corner seems to conceal an unspeakable secret. While investigating, Li discovers strange symbols and clues that appear to point to a terrifying experiment long since forgotten. As he draws closer to the truth, the horrors in the hospital become more frequent and intense. Ghostly whispers and sinister apparitions keep appearing, trying to frighten him away. But Li refuses to back down. With unwavering conviction and sheer determination, he searches through the darkness for traces of the truth. What he doesn't know is that an even more terrifying conspiracy lies behind it. If uncovered, it could bring an unimaginable disaster. Can he solve the mystery of the abandoned hospital and escape the clutches of terror in this deadly pursuit? The answer remains uncertain.
