Once a wildly popular action star known for his zombie films, Qian Xiaohau (played by Qian Xiaohau) sees his career and life hit rock bottom. He moves into a rundown old apartment with his few belongings. Guided by security guard Uncle Yan (played by Lu Haipeng), he enters the infamous unit 2442 rumored to be haunted.
