VIETNAM VETERANS QUESTIONED IN DEATH -- When a down-and-out Vietnam veteran is murdered, Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) find that although the decorated victim was considered a hero, he was conflicted about his involvement in the conflict. But as Executive A.D.A. Jack McCoy (Sam Waterston) and A.D.A. Serena Southerlyn (Elisabeth Rohm) learn about other members of the dead man's fighting unit, they investigate some more successful civilians who once served with him.
