Synopsis: Kwon Taek-joo, an ace agent of the National Intelligence Service, is dispatched to Moscow to find out the identity of 'Anastasia', a deadly weapon that Russia and North Korea are secretly working on. The NIS assigns a local intelligence source named "Zhenya" as a partner to him, who is new to dispatching to Russia. 'Zhenya', who seems to be in close contact with Russian political and business figures as well as the underworld mafia, always pretends to be relaxed and cheerful, but suddenly reveals his tyrannical nature, making it impossible to relax for a moment. Meanwhile, 'Zhenya' begins to take a special interest in 'Kwon Taek-joo', who does not know how to break through the storm.
