Grissom (William L. Petersen) and Sara (Jorja Fox) get more than they bargained for while investigating the kidnapping of a millionaire's wife (Jolene Blalock) in the desert. Back in Vegas, a 14-year-old girl is killed in a hit and run. Using the slimmest of leads, Catherine (Marg Helgenberger) and Warrick (Gary Dourdan) go after the perp. ~ Hal Erickson, Rovi
