PLOT
Eight years ago, Jiale, a senior member in the gang, takes the blame for his brother and goes to prison. After his release, he wants to live peacefully in a small coastal town, away from the underworld. However, his former boss, Rong, intends to hand over the gang to him, while Huoshan, who rose to power thanks to Jiale's sacrifice, sees his return as a huge threat. As power, lies, and old grudges intertwine, Jiale has no choice but to return to the underworld. Along the way, he saves Jiehe, a girl with a music dream on the verge of despair, and she becomes a glimmer of light in his dark life. To protect the ones he cherishes and account for his past, he picks up the knife again. A thrilling gunfight breaks out in the dark alleys of the city, and he turns the tables time and again with his skills. Tearing off Huoshan's disguise, the truth from eight years ago comes to light.
