Synopsis by Hal Erickson
The man who has just won 400,000 dollars at one of Sam Braun's casinos has a foolproof "system": he cheats. Later on, the man is found murdered, along with his accomplice. Inasmuch as Braun (Scott Wilson) is a prime suspect, Grissom (William L. Petersen) takes Sam's biological daughter Catherine (Marg Helgenberger) off the case -- as if that would stop her from trying to get Sam off the hook. More friction occurs within the CSI staff when Nick (George Eads) beats out Sara (Jorja Fox) for a promotion.
