FRONTLINE tells the dark tale of the men of Third 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. This program contains graphic language, imagery and descriptions of violence. Viewer discretion is advised.
