One man's deadly hunt for justice is about to become the year's most gripping serial killer thrillers. 

Xuan Lang is the last surviving member of his family, a man with nothing left to lose. His family was brutally murdered at the end of the Vietnam War by a group of seven US soldiers. Now, he heads to the United States to hunt down the men who took everything away from him.

The rogue soldiers have been hiding their dark secret from the military - and their families - all these years, but the past has a way of catching up with you. 

There are only two ways out: death or revenge. Who will be the last man standing?
