Na Cha stars Fu Sheng as the prodigal son of a wealthy local official. When obnoxious sea dragons take on human form and cause trouble on the land, he realizes that the common people need help and takes up his mantle as their protector, fighting the dragons and their flunkies with the aid of supernatural powers.
