A private security company, SPARO, is responsible to create Personal Security Teams in Mosul, Iraq. To fill the positions on those teams, SPARO turns to professional soldiers who have the warrior skills needed to handle the dangerous runs that they will make into the enemy-filled Red Zone.

SPARO's new teams, designated as "Spartans", find themselves in life-threatening challenges every time they roll through the gates of the Forward Operations Base and into the Red Zone. The Spartans are in a constant struggle to out think, out maneuver and out fight the enemy on a daily basis.

The story focuses on one Spartan in particular, Jesse. Jesse left his foreign wife, Rini, and their son, Ronny, in Hawaii to go on this mission to Mosul. As Jesse deals with the stress of war and running on dangerous missions with the Spartans, his wife and son deal with the challenges of living in a foreign country. The extreme cultural differences, language barriers and being alone take their toll on the young and beautiful Rini. She struggles to learn the American way of life while at the same time living in fear that her Jesse may never come home.
