The life of one couple in China is forever changed when their 15-year-old son, Zhang Shuai, is convicted of robbery. Desperate for her son to have a chance at a happy life, his mother sells one of her kidneys in order to offer a bribe to the judge's lawyer for a lighter sentence. The lawyer keeps the money, however, and Zhang Shuai spends three years in prison. Now a free man, Zhang Shuai is livid at the world for the three years of his life lost to a prison sentence and for his mother, who died after the loss of her kidney. Now he is hell bent on finding revenge, but he may not know the truth before he begins his rampage.
