Lu Yanzhou is a technological upstart in the eyes of outsiders, but he is the humblest cash machine in his native family. He is extremely stupid and filial, and responds to his parents' requests, but is cold and harsh towards his wife Su Nian. He acquiesced in allowing his mother to take away the salary card and forced his pregnant wife to hand over the marital home. Even when his wife and younger brother had an accident at the same time, he did not hesitate to choose his younger brother, causing Su Nian to have a miscarriage and lose her fertility. Even so, Su Nian still had the last illusion about this marriage. Until that afternoon, she signed the divorce agreement and left in despair with the fetus in her belly. While making her last call for help to Lu Yanzhou, she was involved in a car accident, killing one person and two others. At this time, the mother's collection call arrived before the news of his wife's death. Lu Yanzhou's "awakening" started with the string of cell phone ringtones at the door of the morgue. Holding Su Nian's ashes and diary, he embarked on a bloody road of atonement and revenge.
