The useless person who was reviled by the entire Internet has turned into ashes. His handwritten confession of seven deadly sins written in prison shocked the whole country. Every word is like blood and every sentence is a mystery. Former detective Jiang Zhao discovered that these 'crimes' perfectly overlapped with a serial case that had not been solved for three years. Sister Lin Fei wants to silence her, hacker Xie Zhiyao secretly adds fuel to the flames, mute prison guard Zhou Ya silently hands over a pen, and psychiatrist Chen Yan is quietly increasing his dose of sedatives. When the last chapter of the confession pointed to the real name of the 'executor', Shen Jin knew that what he wrote was not a confession, but a will. And Jiang Zhao is becoming the next target.
