Fan Tung (Liu Kai Chi) is one of the four deities under the Stove God. He has offended the Queen Mother of the West of being ravenous and gets imprisoned for 500 years in the winter melon. By chance Tin Tai Kwai (Sunny Chan) and his wife Chung Pik Yuk (Louisa So) free him from constraint. Tung has crashed with Tai Kwai's older brother Tin Tai Fu accidentally and his spirit enters Tai Fu's body inexplicably while losing all his instincts. Tung starts living in Kwai's house and gets closer to the family. Yuk finds Tung suspicious and she tries to unmask him by all means. Having failed in his attempt to return to Heaven, Tung becomes reliant on the help of six little deities who assimilated his instincts released from the melon, and since then Tung is aware of the fickleness of human nature. One day, Fu's truant wife Ling Fung (Rain Lau) suddenly returns. She ruins everything and even causes the death of Tai Kwai. In order to get his life back, Tung illicitly breaks into the netherworld. --Astro on Demand
