Grissom (William L. Petersen) and Catherine (Marg Helgenberger) investigate when a wealthy couple, Calvin and Monica Newman, are found murdered outside the expensive Las Vegas house that they had hoped to sell. Suspicion falls on someone very close to the couple, as well as another person who at first seemed startled by the discovery of the bodies. Meanwhile, Sara (Jorja Fox) looks into the grisly death of teenage cheerleader Amanda Kirk, whose cannibalized body was found on a high school soccer field. ~ Hal Erickson, Rovi
