The Mastermind Behind the Guns: Moon Baek is not a helpful informant; he is the mastermind who engineered the entire gun distribution network across South Korea.
Moon Baek’s Origins & Illness: As a child, Moon Baek was a victim of human trafficking sold to an American arms dealer, instilling hatred for a society that abandoned him. Suffering from terminal cancer, he uses his connection to the International Rifle Union (IRU) syndicate to unleash chaos as his final legacy.
Captain Jo’s Death & The Standoff: In Episode 8, Captain Jo is killed by syndicate enforcers. In Episode 10, Moon Baek hosts a "Free Guns" event in a foggy public plaza to force a civil riot. When taunted to shoot, Lee Do lowers his firearm, steps into crossfire, and shields a child. Inspired, the crowd drops their weapons. Moon Baek is critically wounded and falls into a coma.
Season 2 Teaser: Lee Do adopts the young boy he saved. In the final scene, a mysterious blonde operative from the IRU arms syndicate enters Moon Baek’s hospital room, hinting that the global arms campaign in Asia is ongoing.
