In this conclusion of a two-part story, the detectives and the lawyers vow to avenge the slaying of a woman whose son witnessed a Russian Mafia hit. Relentlessly digging up every possible lead, the forces of law and order endeavor to expose a widespread money-laundering scheme -- and to prevent any more killing of witnesses or destruction of evidence. As ADAs McCoy (Sam Waterston) and Carmichael (Angie Harmon) risk violating the civil liberties of witnesses by keeping them in protective custody, detective Curtis (Benjamin Bratt) is hit with a tragedy in his own household. Both parts one and two of "Refuge" were broadcast May 25, 1999, as the finale of Law & Order's ninth season -- and, incidentally, as the swan song of series regular Benjamin Bratt. ~ Hal Erickson, Rovi
