Synopsis by Hal Erickson
A few episodes back, casino owner Sam Braun (Scott Wilson), biological father of CSI member Catherine (Marg Helgenberger), presented her with a huge check, presumably for helping him beat a murder rap. In this episode, we find out more about that check -- and a lot more about Catherine, especially during her job evaluation. In addition, some surprising "dirt" about Catherine's colleague Sara (Jorja Fox) is also revealed. Meanwhile, the CSI investigates the double murder of a well-liked Vegas club owner and his porn-star wife, which may or may not be linked to a huge jewelry heist.
