Trouble abounds for J.D. (Zach Braff) and Dr. Cox (John C. McGinley) when they feel threatened by a patients' daughter, Neena Broderick (special guest star Julianna Margulies), a malpractice attorney with seemingly evil intentions. J.D. finds great difficulty in escaping her flirty and conniving ways. Meanwhile, Elliot (Sarah Chalke) attempts to hide Doug (guest star Johnny Kastl) from Neena due to his tendency to cause medical malpractices. Elsewhere, Turk (Donald Faison) pulls a fast prank on the Janitor (Neil Flynn) and doesn't like the payback he receives from him and Mr. Korman (guest star Richard Kind, Spin City), a former patient who tries to get retaliation. Judy Reyes and Ken Jenkins also star.
