In the premiere episode of CSI: Crime Scene Investigation, Jim Brass (Paul Guilfoyle), head of the Las Vegas PD's forensic team, resents the presence of novice team member Holly Gribbs (Chandra West). Brass' efforts to scare Holly result in tragedy, but not before the unit investigates a disturbing variety of crimes: overnight-shift head man Grissom (William L. Petersen) looks into a suspicious suicide, number-two team member Catherine Willows (Marg Helgenberger) joins Warrick Brown (Gary Dourdan) in probing the death of a not-so-homeless drunk, and Warrick's friendly rival Nick Stokes (George Eads) searches for a woman who drugged and robbed a hapless tourist. ~ Hal Erickson, Rovi
