synopsis
As Las Vegas swelters under a triple-digit heat wave, Catherine (Marg Helgenberger) investigates the death of a baby, whose body was found locked in a car. Apparently the infant died of suffocation -- but when exactly did the death occur? Likewise yielding more than meets the eye is Warrick's (Gary Dourdan) investigation of a man who allegedly succumbed to a heat stroke. And Nick (George Eads) and Sara (Jorja Fox) arrive on the scene when a young girl's body washes up along a lake shore.
