With the Korean Peninsula under Japanese rule in 1930s, many Koreans flock to Manchuria for refuge. Some become bandits, some train robbers and yet others bounty hunters. While the Weird, a notorious train robber, is stealing from a Japanese train crossing the Manchurian plains, he discovers a treasure map. But the map is also sought after by the Bad, a merciless gang leader. Coincidentally, the Good, a bounty hunter, is on the train, and he is after the Bad. The three engage in a spectacular chase with the Japanese Army, the Korean independence fighters, and the Chinese bandits all looking to get their hands on the prized map.
