The fate of prisoners of war and missing in action is one of the darkest chapters of the Cold War. Tens of thousands of American soldiers European survivors were sent to unknown destinations during World War II, the Korean War, and the Vietnam War.
American soldiers captured in the Cold War - the enemy needs them as hostages and bargaining counters. Their own government denies their existence, leaving them to their fate.
For years it was an open wound for thousands of families in the United States - the search for forgotten prisoners in the Vietnamese jungle, the boys who were left behind.
The boys who scratched codes in the earth in desperate attempts to make contacts with home. Attempts that their own government ignored.
