Han Jiajie is a martial arts stunt double in the film and television industry. To fulfill his self-worth, he adheres to his aspiration. Struggling to make ends meet, his girlfriend Tan Yuxin, who is also at the bottom rung of the industry, leaves to become a contracted live-streamer elsewhere. From then on, the two begin a long-distance relationship. However, his girlfriend's career growth renders Han Jiajie even more insecure. With the successive departure of people around him, Han Jiajie is left alone here, and his spirit takes a blow as he feels oppressed by reality. He goes to a bar to drown his sorrows, where he incidentally stumbles upon a young lady named Ou Yingying from a gang who is being assassinated. Han Jiajie intervenes to save her, not knowing that this would have a butterfly effect. As his life becomes increasingly miserable, he also begins to waver. Han Jiajie chooses to follow the Ou family and does things that go against his conscience and violate the law. After a while, Han Jiajie’s kindness is awakened as he witnesses the tragic situation of the victims. He voluntarily turns himself in to the police, and with his cooperation, the police successfully take down the Ou gang.
