When U.S. Marine Gabriel Drummer returns home from his tour in Afghanistan, he finds that the place he once called home is no better than the battlefields he fought on overseas. Accompanied by his best friend, Devin Roberts, a hard-nosed Marine whose natural instinct is to shoot first and ask questions later, he searches desperately for his estranged wife Natalie and their son. In their search, the two intercept Charles, a man carrying vital information about the whereabouts of Gabriel's family.
