The plot of this movie is set against the backdrop of the new leadership in North Korea. I'm not too familiar with the internal politics of the North Korean leadership, but it is interesting to see it being dramatized. This show has a really stellar cast - Ha Jung Woo (great action movie hero), Jeon Ji Hyun, Han Seok Kyu and Ryu Seung Beom (deliciously hot and villainous villain). They all play their roles well. I also love the fact that the movie is set in Berlin, a city I have visited and really love, but its significance probably lies in the fact that people from all over the world converge in this city. Initially, the story was a little bit difficult to follow because so many parts of it are unspoken, and there were so many players in the story. However, thankfully I managed to catch on. There is a lot of English and German spoken in this movie - some of the English was really awkward, but it was watchable. As with any Korean show, there is a love story at the center of it all - Ha Jung Woo and Jeon Ji Hyun's characters who are husband and wife. On the whole, a really exciting watch!
