David Loman, a simple country bumpkin who accidentally becomes a big boss in the criminal underworld. A decade passes, and life seems to go on as usual - solving daily problems for locals and receiving "protection fees" - until one day a deity tells David through a medium that he needs to find a double to avoid a catastrophe. Panicky, the boss seeks help from Old Ho, who agrees to pass as David for a few days, but is assassinated when attending a gathering with fellow gangsters.
Now retired from the criminal underworld, Loman runs a bed and breakfast with his loud, boisterous family. The plot is built around various domestic situations - a relationship crisis between Loman's daughter Jin and her partner Xiao Ho, as well as unresolved issues between David's wife and her younger sister Hottie. Hong Kong's big boss Brother Tien soon arrives to meddle in everyone's affairs.
