Shortly after American soldiers learn that their unit is set to return home, they are deployed on a final humanitarian mission to deliver medical supplies to a remote village in Iraq. Among the team are Lt. Col. William Marsh (Samuel L. Jackson), SGT Vanessa Price (Jessica Biel), SPC Tommy Yates, SPC Jamal Aiken (50 Cent), and PVT Jordan Owens. Tragically, their journey takes a dark turn when they fall into an insurgent ambush.
During their precarious passage through a narrow street, the convoy is struck by enemy fire. The rear vehicles manage to veer off to evade the initial attack but soon collide with a hidden improvised explosive device disguised within the remains of a dead dog. In the chaos, SGT Price sustains severe injuries while her front-seat passenger is killed instantly protecting her from the explosion. The team pursues the attackers, only to suffer more losses as one of their own is shot down. Aiken injures himself while attempting to engage the enemy, leaving Yates and Owens to advance alone toward the gunfire.
As Yates is wounded, Owens rushes after the assailant, but is shot from behind before he can retaliate. Yates finds Owens bleeding and, despite his efforts, is unable to save him. In a scene filled with tension, a mortar attack at a nearby field hospital leads to further casualties and chaos. Amidst the panic, Dr. Marsh faces an emotional crisis when a distraught soldier threatens him at gunpoint, demanding immediate attention for their injured comrade.
The fallout from their traumatic experiences affects each soldier deeply upon returning to civilian life. Price grapples with newfound limitations as she attempts to adapt her role as a P.E. teacher with one hand. Yates faces obstacles in employment after returning from war, while Aiken struggles to navigate the complexities of his mental health post-deployment. Dr. Marsh finds himself on a slippery slope towards self-destruction as family issues arise, leading him to consider therapy for post-traumatic stress disorder (PTSD).
As conflicts unfold, Aiken is shot by police during a standoff at a diner, highlighting the vulnerabilities faced after returning home. Yet, amidst the turmoil, Price finds solace with a new romance, while Yates re-examines his future and decides to re-enlist, motivated by a desire to protect fellow soldiers from facing similar hardships.
As the story resolves, we witness a glimpse of hope: Marsh’s son joyfully playing soccer at Price's school, signaling a sense of community and healing. The film closes with a poignant reminder of the war's enduring impact through a quote by Niccolo Machiavelli: > "Wars will begin where you will, but they do not end where you please."
