In Korea's wild west (Manchuria in the 1930s). The Japanese took over, Koreans were Japanese citizens and next door, every Korean bad guy, outlaw, con man, and treasure seeker was running crazy across Manchuria. This movie has various Korean gangs, Manchu outlaws, and the Japanese Army all looking for the same treasure.
If you don't mind sub-titles, this is a great beer and popcorn movie.
