Kang-in is de directeur van de overzeese tak van de National Intelligence Service. Hij leidt een team met de beste agenten bij het uitvoeren van geheime missies. Zijn bijnaam is Yaksha, een mens-verslindende geest, omdat hij genadeloos te werk gaat om te krijgen wat hij wil. Op een dag verschijnt aanklager Ji-hoon in zijn leven om het speciale team te onderzoeken. De officier van justitie ontdekt dat Kang-in's team verwikkeld is in een dodelijke oorlog tussen spionnen.
