Rescue

Concussed during an artillery barrage and separated from his platoon, Hanley starts to come out of his daze only to find he is being taken prisoner by an SS soldier. The first twist is when the SS soldier is shot by another SS soldier who frees Hanley. Then we learn the second SS soldier is really a GI corporal who just escaped from a holding area, but his wounded Colonel is still being held by the Germans and has information valuable to the Germans.
