Li Ching is the Seventh Sister, an angel who comes down from heaven to see what life in Hong Kong is like. In Hong Kong, she runs into Zili(Chin Feng), a reincarnated version of her deceased lover, Dong Yong. Zili, with help from cook Uncle Bull(the warm, portly Peng Peng), do their best to watch over homeless kids in an run-down orphanage. However, a heartless tycoon named Xu Caifa wants the land where the orphanage is and he's willing to go to extremes to get it. Armed with omnipotent powers, spirit, and help from her "celestial sisters", Seventh Sister works to defend Zili, Uncle Bull, and the orphans from Xu Caifa.
