CSI: Crime Scene Investigation is an innovative, fast-paced drama that follows a crew of forensic investigators as they solve crimes by analyzing evidence with advanced forensic tools. Many of the shows are loosely based on real-life events, police cases, and situations.

The crew is headed by Gil Grissom (William Petersen), the senior investigator devoted to find the truth through the latest forensic methods combined with old-fashioned research and intuition. Alongside Gil is Catherine Willows (Marg Helgenberger), a single mother struggling to balance her home life with the rigors of her demanding job; Warrick Brown (Gary Dourdan), whose knowledge of the gambling world helps the Las Vegas based crew; Nick Stokes (George Eads), a self-proclaimed ladies man with an objective to find the wrong-doers; and Sara Sidle (Jorja Fox), the newest, outspoken member who often lets her troubled past get in the way of her job. The crew works along side Captain Jim Brass (Paul Guilfoyle), the former head of the graveyard shift turned captain; Greg Sanders (Eric Szmanda), a quirky lab tech switching to a field operative; and medical examiner Dr. Robbins (Robert David Hall).

This cutting-edge drama, now ending its ninth season, has been the number one scripted series for four years running, and shows no sign of slowing down any time soon. Changes introduced with/during the ninth season are the loss of three cast members (Gary Dourdan, Jorja Fox, and William Petersen) and the inclusion of another in the person of Doctor Raymond Langston(Laurence Fishburne), a medical doctor with an interest in forensic medicine, who decides to take a major pay cut and join the hands-on side of the job as a CSI level one.
