Synopsis by Hal Erickson
Sam Waterston joins the cast as Executive Assistant D.A. Jack McCoy in Law & Order's fifth-season opener. The case at hand is a "revolutionary" breast-cancer treatment that may have caused a woman's death. The D.A.'s office pursues the woman doctor who developed the treatment -- and who may very well be the "quack" that her colleagues have claimed her to be. In his pursuit of the accused, Jack McCoy demonstrates early on that his zeal for justice does not always adhere to the letter of the law.
