Marine Major Sam Hanson refuses a presidential order to surrender his battalion to be butchered by ISIS when they overrun the Mid-East. He is reduced in rank and transferred to a company of Marines that provides security to the hospital complex in New York City where he becomes friends with Dr. Carver.

A deadly terrorist attack kills Hanson's son and Carver's daughter. They make a plan to identify the terrorist cell and target a safe house in Brooklyn. There they discover nuclear material intended for a dirty bomb. When government agencies downplay the threat of more nuclear material, Hanson pledges to help the new President avoid a nuclear disaster.
