A teenager is found dead in his motel room, the cause of death: millipede poison. . . Now crime scene investigator Gil Grissom must aid CSI's Nick Stokes and Riley Adams against a serial killer whose knowledge of entomology rivals his own -- a brutal murderer who is not only using insects as the tools of destruction, but actually modeling the attacks after their behavior. . . In the meantime, CSIs Catherine Willows and Greg Sanders must investigate a bizarre death, where the victim had gotten mixed up with two very different groups of people -- one involved in using and dealing crystal meth, the other an avant-garde group of artists -- a collision of subcultures where everyone is a suspect and nothing is as it seems. . .
