Dentist Gus Sugarman is stabbed in the back of the head by a screwdriver while sitting in a crowded movie theater. Grissom (William L. Petersen) and Catherine (Marg Helgenberger) follow up two possibilities: that the killing was committed by an elusive red-headed woman and that Sugarman was not the intended victim. Elsewhere, the other CSI agents are stymied by the reams of contradictory evidence attending the death of teenager Timmy McCallum, whose badly beaten and bullet-ridden body was found in a warehouse where 100 rounds of ammunition were fired from every conceivable angle.
