A college fraternity pledging ends in tragedy when a rejected student apparently commits suicide. Nick (George Eads) and Sara (Jorja Fox) discover that the case is not as open-and-shut as it seems. And while looking into the discovery of a woman's body -- with one leg missing -- Grissom (William L. Petersen) and Catherine (Marg Helgenberger) conclude that either the victim's husband or her boyfriend might have had a hand in her death. ~ Hal Erickson, Rovi
