CONDUCT UNBECOMING -- An investigation into the murder of a Navy officer helps Detectives Briscoe (Jerry Orbach) and Curtis (Benjamin Bratt) crack a rash of murder/muggings. But when the two cases are proved unrelated they find themselves up against the Navy. Later, McCoy (Sam Waterston) and Ross (Carey Lowell) do battle to win jurisdiction and confidential information. Patti LuPone reprises her role as defense attorney Ruth Miller. S. Epatha Merkerson and Steven Hill also star.
