Lin Jianqing, a third-year university student, buys an old Polaroid camera, only to discover that it can capture a “countdown to death” above other people’s heads. When his roommate’s countdown reaches just 72 hours, Lin Jianqing is forced into a terrifying game spanning two decades. Campus legends and urban ghost stories begin to resurface one after another, while a blood-written warning appears on the back of the camera: “Find us, or become one of us.” As he flees and tries to break the curse, he discovers that every clue points to an ancient entity that feeds on fear, and that he himself is the key prey in this hunt.
