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.
A series of deaths in one shift, including a man found dead on his couch and a recently divorced man found in a pool, instigate a bet among the CSIs.
While investigating a woman's death, Sara and Langston turn to a friend of Grissom's for help; after a teenager appears to have committed suicide, Nick and Dr. Robbins save her unborn baby.
For the first time since he escaped, the infamous "Dick & Jane" killer resurfaces with a threatening video.
Nate Haskell, the infamous "Dick & Jane" killer kidnaps Langston's ex-wife and leaves a message written in blood.
