The storylines remain as compelling as ever, but this seventeenth season of Law & Order brings big changes to the men and women working in New York City's criminal justice system. Ed Green (Jesse L. Martin) earns his promotion to Senior Detective, Nina Cassady (Milena Govich) joins the Department for her short tenure as a detective, DA Arthur Branch (Fred Thompson) finishes his time as the District Attorney and Jack McCoy (Sam Waterson) serves his final days in the courtroom before taking on his boss's position. Featuring all 22 gripping episodes, with cast members S. Epatha Merkerson and Alana de la Garza, and notable guest stars Chevy Chase (Community), Mariel Hemingway (Manhattan) and Mario van Peebles (Damages), it's a vital chapter in the Primetime Emmy® Award-winning success story from iconic producer Dick Wolf. © 2011 Universal Studios.
