Heading the unit in Grissom's (William L. Petersen) absence, Warrick (Gary Dourdan) is all but overwhelmed by his new responsibilities. Warrick's biggest headache occurs during the investigation of the drug-related murder of a con artist (John Fugelsang). As the clues are assembled, a prime suspect emerges: Ellie Brass (Nicki Aycox) -- the spiteful and rebellious daughter of former CSI head Capt. Jim Brass (Paul Guilfoyle). Compared to this development, Sara's (Jorja Fox) investigation of a counterfeiting ring is practically a walk in the park...practically. ~ Hal Erickson, Rovi
