An ER doctor (Mimi Kennedy) is suspected of withholding vital evidence in the mysterious shooting of a burglar. An enormous man who has gone on a rampage proves to be a major challenge for Lewis (Clark Johnson) and Kellerman (Reed Diamond) -- and also indirectly exposes a number of skeletons in the closet of Lewis' family. And Munch (Richard Belzer) is continually frustrated in his efforts to find out whom Howard (Melissa Leo) is dating. ~ Hal Erickson, Rovi
