The down-and-out swordsman Shen Juan and the gluttonous, cowardly dog "Dog Lord" accidentally intercept a martial arts secret order because of snatching a piece of braised bone, becoming embroiled in a Jianghu conspiracy. The man and the dog inexplicably take the blame for murdering the envoy and stealing a supreme treasure, becoming wanted by the entire Jianghu and forced to embark on a hilarious escape. To clear their grievances, Shen Juan and the female constable Ye Zhaoshuang investigate all the way, not only uncovering the truth about the tragic death of Master in Yanhui Valley twelve years ago, but also shattering the shocking layout of the mastermind, Martial Arts Alliance Leader Gu Tianheng, who attempted to manipulate both the righteous and demonic factions. Ultimately, Shen Juan suppresses the Jianghu with a single sword at the Tianmen Assembly, subsequently refuses to take up the post of Alliance Leader, and continues to roam the world freely with Dog Lord.
