CSI: Crime Scene Investigation returns to the scene of the crime for it's fifteenth and final season. From a lethal chemistry classroom to a fatal medical marijuana clinic to a deadly memorabilia convention, the evidence leads to Sin City's most twisted corners. Whatever the case, lead investigator D.B. Russell (Emmy winner Ted Danson) knows he can rely on the brilliance of blood-work expert Julie Finlay (Oscar nominee Elisabeth Shue) and veteran investigators Nick Stokes (George Eads), Sara Sidle (Jorja Fox) and Greg Sanders (Eric Szmanda). Yet the final challenge is darkest for the elite team of experts, including Robert David Hall, Wallace Langham, Elisabeth Haranois, David Berman, and Jon Wellner, when a serial killer stalks Las Vegas and his traps threaten to ensnare one of CSI's own. The pulse-pounding suspense never let's up in the 18 gripping episodes of this 5-disc set that bring the breakthrough series to an edge-of-your-seat finale.
