The story of a huge incident faced by Seo Soo-yeon from the support management team that supports and manages NIS field agents in China, Jang Cheon-woo, a hidden NIS black agent and Do Jin-sook, deputy director of overseas parts.
It was too expensive to keep Namkoong for another 2 episodes so we got this instead. These sloppy 2 episodes further highlight the worst points about the original series. Soo Yeon once again proven to be the worst character. We got less violence and a worse story, action and performance. If you barely got through the original one then I recommend skipping this useless prequel.
