Grissom (William L. Petersen), Nick (George Eads), and Sara (Jorja Fox) would seem to have an open-and-shut case on their hands when a suspect is caught burying a body that has been shot three times. But, despite an overwhelming amount of evidence, Grissom doubts that the suspect is the guilty party. And in another development, Catherine (Marg Helgenberger) and Warrick (Gary Dourdan) must determine if a woman found dead in a health spa locker room was a victim of natural causes, murder -- or something else. ~ Hal Erickson, Rovi
