Pretty badass Korean flicker, definitely worth checking out. Here's a better review, but I don't want to say too much other than I liked it very much. Basic synopsis is that a Korean from the Yanbian Korean Autonomous Prefecture (a no-man's land in a wedge between Russia, China, and North Korea) is coerced into traveling to South Korea to execute an assassination.
