This is a fast paced, gritty spy thriller from the Korean director Ryoo Seung-wan. Basic plot: North Korean spy and wife, based in Berlin, are caught in a web of inter-agency cross and double cross. The plot gets a little hard to follow at times, but all comes together about midway through the film, and when it does, the film pays big time. Through the roof action gets the heart pumping. A top notch must see!
