Fortress

July, 1943. US bomber squadrons are bombing Sicily in preparation for the Allies' invasion. One such bomber is the Lucky Lass, a B-17. When her commander is killed, the co-pilot, Lt. Wally McAlister, is given command of the plane. A rookie co-pilot, 2nd Lt. Mike Schmidt, joins the crew. Schmidt immediately alienates himself by not joining in and making some very basic errors on missions. Now he must regain their trust and support.
