PRISON MELEE ENDS IN MURDER -- When a gang leader convicted of brutal crimes is stabbed to death in a prison scuffle, Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) find that their victim had numerous enemies on both sides of the law. The investigation -- in which gang members, corrections officers, and undercover cops are all suspects -- results in an eventual indictment that leaves A.D.A. Jack McCoy (Sam Waterston) with an uphill battle as he tries to convict the murderer of a vicious criminal. Donna Hanover ("One Life to Live," "Superstar") appears as trial judge Deborah Bourke.
