In the coal towns of 1970s Pennsylvania, three generations of the Kowalski family confront the question that has haunted them for decades: why do men fight? When former boxer Danny Kowalski returns home for his father's funeral, he unearths letters from his grandfather—a war deserter—that shatter the family's mythology of masculine honor. As Danny's own son drifts toward a street gang, Danny must decide whether violence is inheritance or choice. Spanning the trenches of Normandy to the boxing rings of Rust Belt America, Why Men Fight is a piercing meditation on rage, tenderness, and the quiet courage of lowering one's fists.
