"Kwon Taekjoo, go to Russia. And find 'Anastasia'." The ace of the National Intelligence Service, 'Kwon Taekjoo', was urgently dispatched to Moscow for a mission to identify and uncover 'Anastasia', the lethal weapon created in a secret partnership between Russia and North Korea (a.k.a DPRK). But, just as he gets dispatched to handle the work in Russia for the first time, things immediately go south, and a man named 'Zhenia' who appeared and introduced himself as a local partner assigned by the NIS, makes Kwon Taekjoo even more confused. 'Zhenia', who appears to be an influential figure among Russian business and political figures as well as having connections with underworld mafias, seems to always be laid-back and cheerful. But at the same time, his violent erratic temperament keeps Kwon Taekjoo on edge. Meanwhile, 'Zhenia' starts showing a newfound interest in 'Kwon Taekjoo', who feels unperturbed by any hardships.
