When a group of international rebels target a massive oil refinery in Iraq, a private Chinese security team led by Commander Luo (Chan) volunteers to escort nearly 500 civilians to safety in Iraq’s Green Zone. To get there, they must travel via bus along one of the most dangerous roads in the world. On the way, they’re attacked by a team of mercenaries, including decorated US veteran Chris (Cena). Initially reluctant to take on the job, Chris accepts the offer after finding out the exorbitant cost of restoring water to the Iraqi village where he lives. As Luo and Chris find out who’s really behind the oil refinery heist, the two join forces to save lives… and kick ass.
