Frontline investigates the violence, depression, and stress exhibited by a platoon of Iraq War veterans whose members who have committed murder, assault, and suicide. Since the Iraq War began, soldier arrests in the city of Colorado Springs have tripled. FRONTLINE tells the dark tale of the men of 3rd Platoon, Charlie Company, 1st battalion of the 506th infantry, and how the war followed them home. It is a story of heroism, grief, vicious combat, depression, drugs, alcohol and brutal murder; an investigation into the Army’s mental health services; and a powerful portrait of what multiple tours and post-traumatic stress are doing to a generation of young American soldiers.
