An airplane is landing in Las Vegas and a man, Kenny Greene, unsuccessfully hits on a beautiful and hot blonde. After landing, eight passengers find that personal objects in their carry-on luggage were stolen. Outside the airport, the blonde is found dead and Nick and Sara process the crime scene. Soon they find that she was thrown from a car in movement. They find also her driving lesson and identify her as Janet Riggins. The first suspect is Kenny Greene, since the surveillance video from the airport shows him running after Janet. He says that he believed she was the thief and stole her cell-phone from her luggage. Hodges finds that her driving license is fake and that she called Nalley Janitorial Service for thirteen minutes. Nick and Sara visit Jefferson Nalley, who tells them that she is Helen Morrison, who was his former classmate and contacted him six months ago. Then she contacted him last night asking for help but he refused since she was married. Meanwhile, the CSIs investigate who might be the thief and find Hank Kasserman, who had stolen US$ 30,000 from her purse. Dr. Robbins learns that Helen was abused by her husband with many broken ribs and other old fractures. Now her husband Allen Morrison becomes the next suspect and Nick interrogates him. But the question remains: who killed Helen Morrison?
"Keep Calm and Carry-On" is a good episode of "CSI". The gorgeous and sexy woman found dead outside the airport has many suspects with motive to kill her but the end is totally surprising. Nick's attitude towards Allen Morrison in the very end of the show is very funny. My vote is eight.
