An ex-special agent Tae-sik Cha's only connection to the rest of the world is a little girl, So-mi, who lives nearby. Her mother, Hyo-jeong smuggles drugs from a drug trafficking organization and entrusts Tae-sik with the product, without letting him know. The traffickers find out about her smuggling and kidnap both Hyo-jeong and So-mi. The gang promises to release them if Tae-sik makes a delivery for them, however it is actually a larger plot to eliminate a rival drug ring leader. When Hyo-jeong's disemboweled body is discovered, Tae-sik realizes that So-mi's life may also be in danger. Tae-sik becomes enraged at the prospect that So-mi may already be dead and prepares for a battle, putting his own life at risk.
