Law & Order Episode 15.14 Fluency

FALSE FLU VACCINE CAUSES NINE DEATHS AS ANNIE PARISSE ('NATIONAL TREASURE') JOINS CAST AS NEW A.D.A. -- When nine afflicted people suddenly die, Detectives Fontana (Dennis Farina) and Green (Jesse L. Martin) discover that the victims were injected with fake flu vaccine that did not protect them, leading the police to arrest a career con man (as Peters, guest star Rob Sedgwick) who's counterfeited everything -- including what should have been life-saving vaccine. But as confident new Assistant D.A. Alexandra Borgia (new series regular Annie Parisse, "National Treasure") joins McCoy (Sam Waterston), she boldly promises justice to the victims' relatives that will be difficult for the prosecutor to fulfill after vital search warrant evidence is tossed out.
