Their exhaustive searches and penchant for mayhem take them from an isolated Thai monastery in the Cardamom jungle to hunt an ex-Khmer Rouge soldier in Cambodia with ties to a family of scientists who want to clone the Buddha, and ultimately, in pursuit of the monk's wife, who has been kidnapped by an Iranian Mercenary and his team in Vietnam, who are funded by a ruthless sheik seeking revenge, and of course, the Buddha relic.
