IN ANCIENT ISRAEL, at the crossroads of the great trading routes, a mercenary named Benaiah is searching for a new beginning.

He has joined a band of outcasts led by a warlord named David, who follows the mysterious Hebrew God. Their ranks are filled with bitter, ruthless men - some bound by loyalty to David, others lured by the spoils of conquest. To the desperate Israelites on the frontier they secretly protect, they are known as "mighty men."

Saul, king of the Israelites, spirals deeper into madness. As he marches north against the relentless Philistine empire, the Hebrew tribes have never been more disheartened - or more in need of deliverance.

Across thirteen harrowing days, from snowy mountain passes to blood-soaked battlefields, Benaiah and his fellow warriors must summon all the courage they have to reclaim their homeland and forge a future for their people.
