This self-destructive life changed because of the appearance of Seo In-hye (Park Ha-sun).

Zhang Taishan's despairing heart was rekindled by the appearance of his daughter. To everyone's surprise, Taishan matched his daughter's bone marrow, and the hospital immediately arranged a date for the operation. At the same time, a huge conspiracy was waiting for Zhang Taishan. He was knocked unconscious at a murder scene. When he woke up, the police arrested him for murder. He understood that this incident was actually caused by the gang boss, and he wanted to take the blame for him and go to jail for him. The difference from before is that now Zhang Taishan has one more concern in his heart, and that is his daughter. There are only two weeks before the bone marrow transplant, and the agreed time is getting closer day by day. Zhang Taishan must escape...
