The purchase, selling, or owning of a gun is banned in South Korea. There are almost zero crime cases involving guns in the country. Things change quickly when illegal guns, from unknown sources, are brought into the country and incidents proliferate.
Lee Do, a righteous detective and former military sniper, now struggles to stop the surge of gun crimes while chasing the source of the illegal firearms. Moon Baek, calm and composed on the surface, is his mysterious partner whose true motives remain hidden. Both men hold a gun for their own reasons.
