Plagued by bad luck since childhood, Jiang Yao was struggling to make it alone in the big city. Disaster struck when he was laid off, followed immediately by a mysterious fire in his rental apartment. After draining his life savings to cover the damages, he was left completely penniless. ​Unable to afford rent, Jiang Yao moved into the dilapidated ancestral home left by his late grandfather. While cleaning the crumbling house, he was terrorized and chased by Shen You, a female ghost guarding the property. In his panicked escape, he accidentally flung open the bedroom wardrobe.
