A movie fan escapes from a labour camp during the Chinese Cultural Revolution and strikes up a relationship with a homeless female vagabond.

Many years ago Mr. Six was a notorious gangster. That was back when there was still such a thing as honour among thieves, when criminals earned respect and maintained principles. These days Mr. Six is all but forgotten, a living relic residing in a narrow alley. One day Six's son, Xiaobo, is abducted by some spoiled punks after he scratches their precious Ferrari. Mr. Six realizes that he must do whatever it takes to get his son back — even if that means returning to the life he thought he had left behind.

Wu-Lin is the successor of an ancient, once powerful Chinese clan, the "Iron Feet." After the death of his master, Wu-Lin leaves his rural village for the City of Stone-Cold looking for his fellow apprentice Jiang Li. Along the way, he becomes the bodyguard of Fei-Fei, the daughter of Jia-Shan Li, the richest family in the city, and quickly gets drawn into a mob war in order to protect her.

The story follows a small-town youth who becomes the henchman to a debt-collector. His life is complicated by a cold and estranged parent-child relationship, and an ambiguous relationship with a young woman.
