In the back alleys cast in the shadow of Korean gangs, a police officer consumed by the fire of vengeance inches closer to the truth. Directed by Joseph Kong Hung, this dark crime drama draws from the harshest and most uncompromising vein of Hong Kong action cinema. In this world where old scores have been settled and betrayal lurks around every corner, the rules are crystal clear. As Sergeant Li and the Interpol agent search for his brother’s killers, they must confront not only the criminals but also their own pasts.
