The Korean peninsula is constantly under political and military tension, especially with the North Korean nuclear issue. To avoid a second Korean War, a secret black ops agency known as the National Security Service (NSS) protects South Korea's national security by training special agents who would use any means to fulfill their mission. They officially do not exist and are not acknowledged or protected by the government. Although they are trained to be cold-blooded killers, there is one taboo they cannot avoid: love. Hyun-jun and Sa-woo were close friends and rivals in the 707th Special Mission Battalion, and both are recruited into the NSS and quickly become the best of the best. Each with different secret assignments, they soon take different paths in life. In a world of conspiracy and betrayal, they both fall for Seung-hee, the beautiful but lethal profiling specialist at NSS. During a terrorist nuclear attack, Hyun-jun and Sa-woo are pitted against each other and faced with a final decision, while Seung-hee's formidable secret is revealed. here to download he movie /1AoSxji
