It's wartime, and the squadron of American soldiers have lost four men so far, whilst managing to capture twenty-two Nazi prisoners. However, there is now a dilemma.

The nine American soldiers are ordered to kill the unarmed prisoners in cold blood, and they have been trained to obey orders without question. Will they disobey?
