Set in the 1930s Manchurian desert, where lawlessness rules and ethnic groups clash, three Korean men fatefully meet each other on a train. The Good, Do-won (Woo-sung Jung) is a bounty hunter who tracks down criminals with rewards on their heads. The Bad, Chang-yi (Byung-hun Lee) is the leader of a group of bandits and can't stand to be second best. The Weird, Tae-goo (Kang-ho Song) is a train robber with nine lives. The three strangers engage in a chase across Manchuria to take possession of a map Tae-goo discovers while robbing the train. Also on the hunt for the mysterious map, are the Japanese army and Asian bandits. In this unpredictable, escalating battle for the map, who will stand in the end as the winner? Never be sure who's good, bad or weird.
