As the Korean peninsula falls into the hands of Japanese imperialists and countless Koreans seek refuge in the vast wilderness of Manchuria, a determined thief, a cold-blooded hitman, and a mysterious bounty hunter all vie for an elusive map that could lead them to a buried treasure from the Qing Dynasty. Tae-gu is "The Weird," a thief who comes into possession of the sought-after map while boldly robbing a train of Japanese military officers. But at the very same time Tae-gu attacks the train, relentless assassin Chang-yi and his violent gang of bandits beset the locomotive as well. Chang-yi is "The Bad," and he'll kill anyone who tries to come between him and the untold treasures of the Qing Dynasty. Just as the cloud of gunpowder begins to clear, a shadowy stranger suddenly appears and rescues Tae-gu from certain death. That stranger is Do-won, "The Good." Do-won has been chasing Tae-gu in hopes that he can capture him and collect the reward money. Now, as these three resolute strangers converge in a sprawling landscape that none of them can truly call home, they quickly discover that Korean resistance fighters, resilient mountain bandits, and the Japanese army also covet the prized map. The fight on the train is only the beginning, too, because when the stakes are this high the action is bound to get bloody.
