Liu Ziying was imprisoned three years ago for drug trafficking. He performed well in prison and had a high cultural quality. He was arranged to write a suicide note to the death penalty inmates. Before he was released from prison, Xu Xiaolong, the death penalty prisoner, wanted Liu Ziying to write a suicide note to him and told him that if he helped him fulfil his will, he would give Liu Ziying a sum of money. After Liu Ziying was released from prison, he acquired money by helping the death penalty prisoners fulfil their will. After tasting the sweetness, he embarked on a road of self-redemption.
