The filmmaker's subjects are patriotic young Americans - ordinary men and women who heeded the call for military service in Iraq - as they experience recruitment and training, combat, homecoming, and the struggle to reintegrate with families and communities. The terrible conflict in Iraq is a prelude for the even more challenging battles fought by the soldiers returning home - with personal demons, an uncomprehending public, and an indifferent government. As these battles take shape, each soldier becomes a new kind of hero, bearing witness and giving support to other veterans, and learning to fearlessly wield the most powerful weapon of all - the truth.
