Corporal Evan Albright is a new recruit who is stationed at a U.S. embassy in a tumultuous Middle Eastern city. He and his team of Marines are tasked with protecting the embassy amidst rising tensions and looming threats. Albright's enthusiasm and desire to prove himself clash with the grizzled, experienced demeanor of his fellow Marines who have seen their fair share of action. The routine assignment quickly spirals into chaos when heavily armed insurgents launch an overwhelming assault on the embassy, putting everyone’s combat skills and courage to the ultimate test.

As the enemy breaches the perimeter, Albright and his comrades must rely on their training and instincts to fend off the attackers and protect the diplomatic staff. With limited resources and mounting casualties, they strategize for survival while awaiting reinforcements. The situation inside the embassy becomes more dire as the insurgents grow increasingly desperate, leading to intense, close-quarters battles. Forced into leadership roles they were barely prepared for, the Marines exhibit remarkable resilience in the face of insurmountable odds. Their valor and brotherhood shine through as they work to fortify their position and counter the relentless waves of attackers.
