Captain Fred Allison has been in a German Prisoner of War Camp for a long time. It has been two years since he last saw Monica, a girl he met, married and bought a house with in six days before leaving for the front. It has also been a very long time since she had last wrote to him. A month after all the prisoners have been put into lock down after a failed prison break, two things change. One is that the camp gets a new commandant and the other is that Fred's oldest and dearest friend Digby shows up. While Fred is happy to see Digby, he says little about Monica, whom Fred speaks of constantly. Unable to tell Fred that Monica had fallen in love with him, Digby escapes back to his own lines. But because of a murder that occured during his escape, he may be facing the trial of his life and also the trial by Fred who found a letter that Monica wrote to Digby.
