This book summarizes a World War 2 mission by retracing the events experienced by the crew of a B-24 bomber on a March 1945 mission over Vienna. The book is based on the first-hand account of the navigator, William W. Edwards, the author's father, and other members of the 783rd Squadron. It provides historical context about the buildup to WWII and the 465th Bomb Group's role in the 15th Air Force in Italy. The narrative focuses on the 166th mission of the group, when the plane carrying Edwards and his crew was hit over Vienna, and the fates of the individual crew members.
