A duel between retro-punk rappers from the white-hot music scene in Las Vegas ends with one of them murdered. The problem for Gil Grissom and his team of crime scene investigators isn''t a lack of suspects, it''s too many - each with his or her own reason to want Busta Kapp dead. But when the suspects start becoming murder victims themselves, Grissom knows he''s got to solve this case in a hurry... before the victim list goes off the charts!
