Jeremy has been looking for his kidnapped fiancée, Katie, for the last four years and returns to Thailand to meet with Lo Jin, a private detective. As they travel in Cambodia, Jeremy lives in a world of regret, re-living flashbacks of his last days with Katie. Lo Jin learns that he has a drug addiction and when Jeremy is robbed twice he begins to lose faith in Lo Jin.
At a local bar, Jeremy meets an American ex-patriot (Carlo) who befriends him and eventually brings him to a brothel. Delirious with pain and pills, Jeremy finds himself locked in a dark room, forced to fend off a brothel girl (Kiri) sent to seduce him. Rejoining Lo Jin in his search, Jeremy is given evidence that they’re very close to finding Katie… until he learns that Lo Jin is also deceiving him.
Chasing Lo Jin through the streets of Siem Reap, Jeremy catches and condemns him. As he returns in a misguided attempt to rescue Kiri from brothel life, the truth of what really happened to Katie four years ago finally reveals itself in an ugly revelation.
