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.

Langston testifies against notorious killer Nate Haskell; Nick gets a call warning him he is in danger and a bomb is found attached to Nick's house.

The CSI team investigates two apparent corpses, only to find that the two men, though initially pronounced dead, come back to life.

When a convicted ex-cop is brutally murdered, the team finds he had in his prison cell a list of people he thought may have killed his wife.

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.
