No Overflix. A Secret Service agent and his brother, a reckless ATF agent, try to stop a group of extreme right-wing U.S. military mercenaries, led by a fanatic Taiwanese vixen, who hijack the Queen Mary 2 ocean liner with the U.S. and Chinese presidents on board with the aim to steal China's nuclear codes to arm China's ICBM missiles to use as bargaining chips for their personal crusade against China.
