Saunders and several other GIs are prisoners in a holding compound. Little do they know Staff Sgt. Mastin played by Claude Akins is really a German plant trying to get information from the GIs before they are sent to a permanent POW camp. Akins is very good at his job of getting the GIs to talk about their own outfits and divulge valuable information. Later, after finding out Akins is really an impostor, Saunders has to figure out how to counteract the damage that has been done.
