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 two people are stabbed at a local motel, the incident resembles two previous crimes that occurred in the same location.

When Finlay goes missing during a spa weekend with Sara and Morgan, the team must figure out what happened.

The team investigates when a murder takes place at an elaborate holiday party complete with real snow and reindeer.

Two bodies are found in a trash bin: one is a man disguised as a cop, who committed armed robbery, and the other is the daughter of a South American crime lord.
