Former U.S. Army detective Mason Collins accompanies a group of Jewish refugees on board an illegal ship bound for Palestine. It is April 1947, a little over a year before the formation of the State of Israel, and hostilities in the region are reaching a boiling point. The British, Jews, and Arabs are all fighting for dominance. Bombings, armed attacks, and assassinations are rife.

Mason joins Laura, the love of his life, in Jerusalem. She's pregnant with his child, and his priority is to get them out of the volatile region. But she has gone into hiding and in fear for her life because of evidence she possesses pointing to a terrifying conspiracy. Then a skilled assassin picks up their trail.

To keep Laura safe, he decides the best option is to run, then tragedy strikes, putting Laura in the hospital with her life hanging by a thread.

Enraged, Mason vows to hunt down those responsible. But how can he hunt for killers in a war zone? Who does he turn to when he can't tell friend from foe?

He's ready to lay down his life to keep Laura safe and bring the killers to justice-his particular form of justice. The problem is, a host of bad actors are determined to see he pays that ultimate price.
