Fourth generation war hero Col. William McNamara is imprisoned in a brutal German POW camp. Still, as the camp's highest-ranking American officer, he commands his fellow inmates, keeping a sense of honour alive in a place where honour is easy to destroy, all under the dangerous, ever-watchful eye of SS Major Wilhelm Visser. Never giving up the fight to win the war, McNamara is silently planning, waiting for his moment to strike back at the enemy. A murder in the camp gives him the chance to set a risky plan in motion. With a court martial to keep Visser and the Germans distracted, McNamara orchestrates a cunning scheme to escape and destroy a nearby munitions plant, enlisting the unwitting help of young Lt. Tommy Hart. Together with his men, McNamara uses a hero's resolve to carry out his mission, ultimately forced to weigh the value of his life against the good of his country.
