During World War I, they called it shell shock. During World War II, they called it battle fatigue. Today, it is known as post-traumatic stress disorder. All are tidy labels for the destruction of a mind. When Angels Wept follows the path of an idealistic young airman's experiences and the horrors he encounters during World War II.

Born in Pasadena, California, Rob Hirsch has been raised with the Midwestern values of his Iowa born parents. He has a respect for life, a belief in the rewards of hard work, and an acceptance of duty. He loves his mother, respects his father, believes in God, and has an abiding trust in his country. He grows up as a well-liked, though somewhat shy child, who develops a fascination with flying and dreams of one day becoming a pilot. With the advent of World War II, he enters the Army Air Force Cadet Pilot Training Program and eventually becomes the captain of a B-17 bomber.

He finds love in a small, rural English village; yet death and destruction are ever-present. It is in the skies over Europe that the horrors of war begin a relentless invasion of Hirsch's psyche, as his mind battles with the reality of a world that suddenly makes no sense. As the Midwestern values he has been raised with become compromised, guilt begins to form fissures in his mind. His respect for life collides with the destruction of life caused by the bombs he drops. When his sense of responsibility is devastated by the death of friends and crew members, the mental cracks widen and become hate filled crevices.
