As usual, one group of CSI members investigates a death, while another group checks up on a second murder. Specifically, Grissom (William L. Petersen), Warrick (Gary Dourdan), and Nick (George Eads) look into a shooting that occurred during a casino heist, while Catherine (Marg Helgenberger) and Sara (Jorja Fox) probe a homicide at a remote desert convenience store. As the team compares notes, it appears as if there is a strong connection between the two crimes. ~ Hal Erickson, Rovi
