Young Union Army private Henry Fleming has dreamed of battle his entire life, but when Confederate forces bear down on his regiment, panic sets in, and Henry flees. Overcome with guilt, he wanders among a group of wounded men coping with the ramifications of combat. Exhausted, hungry, and still reeling between shame over his abandonment and anger at being used as a pawn of war, Henry returns to the regiment. Once there, he discovers that something in him has changed forever.
