Phnom Penh, Kingdom of Cambodia. American diplomat Chris Kelly volunteers for an organization that rescues children from sexual slavery. Chea Phyrom is the nephew of Cambodia's prime minister, and that lucrative trade is his core business. When Kelly threatens his profits, Chea's revenge is swift: he kidnaps Kelly's adopted daughter, Mai, and hides her in his network of brothels. Kelly, faced with a corrupt and ineffective response to Mai's disappearance, falls out violently with the Cambodian-American team leading the investigation. He is forced to take matters into his own hands and, with his marriage, career, and life on the line, race to save his little girl.
