Due to a simple mistake by the God of Wealth, the lives of two men [Mui Choi Kin/梅賽乾(Wayne Lai/黎耀祥)] and [Wong Pak Man/王百萬(Pal Sinn/單立文)] have switched places. Wong Pak Man is now one of the wealthiest men in town, while Mui Choi Kin's life has turned upside down and he is running a street noodle stall by himself after his wife and daughter left him.
As it turns out, Wong Chiu Choi is actually the reincarnation of the God of Wealth. Even though Wong Chiu Choi no longer processes his magical powers, he can still bring good luck to those around him. Yet, Wong Chiu Choi's stepmother [Tsui Sim/徐嬋(Claire Yiu/姚嘉妮)] who turns out to be the reincarnation of an evil frog fairy keeps on standing in the way of his friendship with Mui Choi Kin. She also wickedly arranges [Ng Hiu Ting/吳曉婷(Winki Lai/賴慰玲)] to pretend to be Mui Choi Kin's long-lost daughter to cause further suffering to him.
