Mick (Little Mick) Casey, a tail gunner in WWII, comes home from the war a hero in everyone's eyes but his own. Scarred by the horrors he has witnessed, Little Mick does what many returning veterans do in order to cope-he learns not to feel. Stepping back onto the civilian streets, he assumes the perception of normalcy. He marries, has a family, and tries to make a life in inner-city Chicago. A poignant tale of how a father's inability or unwillingness to heal creates a love-hate relationship with his son, sending the child down a steep path of loneliness and self-destruction. For I Have Sinned continues the saga of the Casey clan, intensely loyal and devoted, but only to each other. Set against a backdrop of war, violence and crime it weaves the history of an ill-fated child's transition from a lonely, inner-city rebel and decorated war veteran to a man who looks all too familiar to him, a man like his father-all earned the hard way.
