"I'm going to terrorise them. Make them weep. Make them wish their mothers had never brought them into this world."

Hunting the murderers of a friend, Choi trades in a freezing Seoul for a balmy South-east Asian town populated with bar fights, drug deals and Russian mobsters. His mission is a simple and decidedly personal one - find the men responsible and make them pay. But when the only road to them becomes more dangerous than he could have ever imagined, Choi finds plenty of candidates who he might end up digging graves for. Including himself.
