When an American cop witnesses his mentor's murder in a trade deal gone wrong, he finds himself on the wrong side of the law in Thailand. But despite the bounty on his head and pressure to leave the country, he teams up with an ex-military mercenary out to settle a score of his own to bring the killers to justice. Their quest for vengeance brings them face-to-face with a band of notorious criminals who vow to take them down if the jungle's natural elements don't kill them first.
