This episode is special because Gil Grissom, Catherine Willows, Greg Sanders and Sara Sidle do not appeared in this episode. This episode is not focus on Las Vegas but in Los Angelos. What is it to do with CSI: Vegas??
Brass gets a phonecall from his daughter, Ellie, claiming that her prostitue friend went missing. Later on, Warrick Brown join Jim Brass to investigate the disappearance of the girl. While Brass trying to locate the girl, he realize his investigation has been interrupted by a higher power. No forensic in this episode, should this episode in CSI: Crime Scene Investigation?
Personally, I HATE this episode, hopefully the writers won't do this again.
