Eleven high school friends in idyllic North Adams, Massachusetts, enlisted to serve in Vietnam, and one stayed behind to protest the war. All were from patriotic, working-class families, all members of the class of 1965 at Saint Joseph's School.

Dennis Pregent was one of them. He and his classmates joined up--most right out of school, some before graduating--and endured the war's most vicious years. Seven served in the Army, three in the Marine Corps, and one in the Navy. After fighting in a faraway place, they saw the trajectories of their lives dramatically altered.

One died in combat, another became paralyzed, and several still suffer from debilitating conditions five decades later. Inspired by his 50th high school reunion, Pregent located his classmates, rekindled friendships, and--together, over hours of interviews--they remembered the war years.
