Logan (Chris Noth) and Briscoe (Jerry Orbach) run up against a "wall of brass" when they investigate the death of a female Navy officer, who was last seen alive at a wild party. The detectives' only witness is Ensign Evan Walters (Michael Dolan), who claims that he can remember nothing of the events leading up to the woman's death. Resistance to the successful prosecution of the case reaches to the highest levels of Navy bureaucracy -- but assistant D.A. Stone (Michael Moriarty) is determined to break through the official coverup. Future E.R. regular Julianna Margulies is seen as Lt. Ruth Mendoza. ~ Hal Erickson, Rovi
