A Hero's Welcome (2008)

After a tour of NATO 'peacemaking' duty in Afghanistan, studly German soldier David gets a warm welcome from his (step)family and his live-in girlfriend Kirsten. But the bedwetting he hides is just an early, minor symptom of a major trauma incurred on the Afghan base. Even the party his stepdad throws him for his silver valor decoration, part of an imposed deal to keep the army's dirty laundry covered up, is cause to lash out angrily. David alternates between protecting his doting kid stepbrother Benni and dragging him into his scary sequence of nightmares, mood swings, and guilt trips.
