GRISSOM AND CATHERINE LEAD THE REUNITED CSI TEAMS AS THEY DELVE INTO THREE COMPLEX FORENSIC MYSTERIES, ON THE SIXTH SEASON PREMIERE OF "CSI: CRIME SCENE INVESTIGATION," THURSDAY, SEPT. 22 ON THE CBS TELEVISION NETWORK

"Bodies in Motion" -- The forensic teams come back together under the leadership of Grissom and Catherine just in time to tackle three complex murder cases, on the sixth-season premiere of CSI: CRIME SCENE INVESTIGATION, Thursday, Sept. 22 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Richard Lewis directed the episode from a story by two of the series' executive producers, Carol Mendelsohn and Naren Shankar, with a teleplay also by Shankar.

Grissom and Catherine lead the team as they tackle three separate investigations: a murdered couple found in bed in a suspicious trailer explosion; a beautiful stripper discovered dead and dumped in the worst part of town; and two bodies found baked and decomposed after spending five days in the trunk of a car exposed to the hot Vegas sun, forcing the CSIs to "wrap" up the evidence and bring it back to the lab for further analysis.

CSI: CRIME SCENE INVESTIGATION, the Emmy-nominated Number One scripted series on television, is a fast-paced drama about a team of forensic investigators trained to solve crimes by examining the evidence. They are on the case 24/7, scouring the scene, collecting the irrefutable evidence and finding the missing pieces that will solve the mystery. Gil Grissom, grave-shift supervisor, heads the team of investigators at the Crime Lab in Las Vegas. The team includes Catherine Willows, a hard-working single parent with a checkered past and a controversial father; Warrick Brown, a top analyst with insider knowledge of the gambling world; Nick Stokes, a true-blue stand-up guy who empathizes with victims via his own experiences; Sara Sidle, a dedicated and inquisitive investigator who has more than a professional interest in Grissom; and Greg Sanders, the wacky tech analyst turned field investigator. The CSI team members also work closely with Capt. Jim Brass, the former chief, now assigned to Homicide, and Dr. Albert Robbins, the ever-professional medical examiner. They are also supported by David Hodges, a lab technician with a specialty in trace and foreign-substance analysis, and Sofia Curtis, whose frustration with lab politics has led her to return to the police force's detective.

CSI: CRIME SCENE INVESTIGATION is produced by CBS Productions and Alliance Atlantis Communications, in association with Jerry Bruckheimer Television. Jerry Bruckheimer, Carol Mendelsohn, Ann Donahue, Anthony Zuiker, Danny Cannon, Jonathan Littman, William Petersen, Cynthia Chvatal and Naren Shankar are the executive producers.
