Speeding motorist Alex Jomes pulls up in front of a casino, gets out of his car -- and dies as the result of the wooden stake driven into his head. It falls to Grissom (William L. Petersen) and Nick (George Eads) to track down the so-called "vampire killer." Meawnhile, Warrick (Gary Dourdan) and Catherine (Marg Helgenberger) follow the trail of clues when the five-year-old son of NBA star Tavian Tombs (Dwayne Adway) is kidnapped while Tombs is having an incredible run of luck at the gaming tables. ~ Hal Erickson, Rovi
