Sometimes children follow in the footsteps of their parents without even realizing it. Kim Sun Woo (Kim Jae Joong) is a genius agent with the South Korean National Intelligence Service whose job it is to monitor and analyze data about North Korea. With a demanding job, Sun Woo gets lots of love and support from his mother, Park Hye Rim (Bae Jong Ok). But there are a lot of things about his mother that Sun Woo doesn’t know, including the fact that she is a former North Korean spy. It is a remake of the Israeli drama “The Gordin Cell.”
