Huang Qiusheng, a fat middle-aged marine policeman, and Gigi Lai, a handsome young columnist, are a loving couple. Hui is taking a long vacation. They had planned to travel to Japan, but before they left, they received a phone call from A Zhi's mother, telling her that something had happened at home. They gave up their travel plans and went to their old house in the countryside of Yuen Long. They met a feng shui master at the door of the old house and told them that the house was at the junction of yin and yang in feng shui. However, they did not care, and still walked into the house. A Zhi's mother (Roland) and sister Affin (Zhang Yushan) live here. The four of them met with strange things that followed, and a family of four was gradually shrouded in a strange atmosphere. They had a grudge against their deranged mother and sister, and finally found out that the female ghost was an unborn child. The last three generations of mother and daughter reconciled and saved the day.
