The Chinese populist faction, the Tuanpai, embark on an audacious plan to trigger a global disaster that will bring down America. In the aftermath, the FBI identifies China as the culprit, but doesn't know if this was a rogue operation or a government plot. The Chinese president knows the perpetrators, but has no proof. Fearful of American retaliation, he invites U.S. investigators to help him find that proof. Under a cloud of mutual suspicion, the investigation stumbles and America readies itself for a military confrontation.
