When a group of international rebels targets a major oil refinery in Iraq, a private Chinese security team led by Commander Luo volunteers to escort nearly 500 civilians to safety in Iraq’s Green Zone. To get there, they have to travel by bus on one of the most dangerous roads in the world. Along the way, they are attacked by a team of mercenaries, including decorated US veteran Chris. Initially reluctant to accept the assignment, Chris accepts the offer after learning of the exorbitant cost of restoring water to the Iraqi village where he lives. As Luo and Chris discover who’s really behind the oil refinery heist, the two team up to save lives… and fight mightily.
