Anna, a photojournalist, travels to Bangkok to pursue her investigations for a news story on the traffic in human beings being carried on by the triads. There she herself is kidnapped by Asian gangsters and subjected to the same abuse endured by the women she has interviewed and photographed. At length, in a Montreal hospital, she awakens to these brutal recollections. Scarred for life, obsessed by her desire for revenge, Anna embarks on a dark journey, where violence beckons at every turn... but the impact provoked by her investigations will prove to be more important than the satisfaction of her own quest for vengeance.
