An explosion inside a casino brings Catherine Willows back to Las Vegas to investigate. And when the crime is tied to Lady Heather, Gil Grissom is brought back as well to aid the investigation. This is a 2 part TV Special. Series Finale
This was a 2 part Mini-Series that aired one after the other. A final episode to close out a great TV series that had multiple spin offs.
Thanks for many years of great entertainment.
