A village mutt named Lie Zui is expelled from his sect. By a stroke of luck, he obtains the long-lost secret art, the Keyboard Heart Sutra. He masters a wicked technique that allows him to kill enemies invisibly just by pounding on a keyboard and insulting them. He establishes his own sect, the Keyboard Hound Gang, and expands at a breakneck pace through handing out flyers and recruiting agents, eventually fighting his way to the summit of Mount Hua. The six great orthodox sects join forces to besiege him, only to be collectively driven to the brink of a breakdown by his sharp tongue and a single keyboard. However, the fatal weakness of his keyboard technique gradually begins to emerge.
