A dedicated group of forensic investigators at the Las Vegas Crime Lab works to solve often-grisly crimes in Sin City. Heading up the graveyard shift (an appropriate term in this case) is supervisor D.B. Russell, a "Left Coast" Sherlock Holmes who devours crime novels. Members of Russell's team include Julie Finlay, Nick Stokes, Sara Sidle (the team's moral compass), Greg Sanders and Morgan Brody. The investigative team works closely with Capt. Jim Brass -- a seasoned detective who is a protector of CSI -- Dr. Al Robbins -- medical examiner -- and quirky lab technician David Hodges. Previous leaders of the group include Gil Grissom and Dr. Ray Langston.

When a major event cripples Las Vegas, Gil Grissom, Catherine Willows and Jim Brass return to help the team; D.B. and Sara consider the future; Lady Heather returns.

The investigation team in Las Vegas scours each scene of a crime to gather forensic evidence; a murderer stages his crimes to look like suicides.

The shooting investigation of Holly Gribbs continues; someone is murdering people who have won millions on slot machines.

It's a race against the clock as Grissom and Sidel investigate the kidnapping of a multimillionaire's wife; Willows and Brown take on a hit-and-run case.
