A house is haunted by the five people that died there recently; since then, no one has dared to go even close to it. Even neighbours are scared by the weird noises that can be heard emanating. Believing there are many evil spectres, spirit medium Tongji (Jen Shuo Cheng) is invited to dispel them. Tongji successfully captures the spectre spirits in a fish!
In summer, the kids are enjoying their school holiday: their mother (Vivian Hsu) prefers that they enjoy the outdoors and run around in nature instead of staying home watching television. One day, the kids decide to go fishing by the river. Unfortunately, they happen to catch the aforementioned demonic fish. The wicked spectres are released again to carry out evil…
