Anx... (more)ious Leo, Nikki and Jack head for the war-torn country in search of the truth about the soldier's mysterious disappearance. Staying in a compound by a small town with ex-military security officer Sean Nugent and his detail, the team discovers that there is far more at stake than simply identifying a soldier's remains.
