CSI – the acronym for Crime Scene Investigation – tells the story of the little-known and less understood heroes who work crime scenes – the forensic investigators. These are the men and women who work 24/7 to untangle the evidence behind the yellow police tape, piecing together seemingly insignificant puzzle pieces to nail the bad guys and serve those who are most important and sometimes overlooked – the victims.
Gil Grissom (William Petersen) is the 17-year veteran who leads the investigators working the graveyard shift for the Criminalistics Bureau in Las Vegas.
His crime lab team includes Catherine Willows (Marg Helgenberger), a street-smart forensics expert who balances her love for the job with her devotion as a single parent to her young daughter; Warrick Brown (Gary Dourdan), a sharp analyst with a passion for his job, yet with an attraction to gambling he knows he has to beat; Nick Stokes (George Eads), who’s got the charm and the chops, and craves the number-one spot on the board for clearing cases; and Sara Sidle (Jorja Fox), the newest member of the team, Grissom’s trusted former co-worker who sometimes plays fast and loose with the rules to get the job done right. The CSI team often clashes with Captain Jim Brass (Paul Guilfoyle), their former chief, now assigned to the homicide division.
Tensions aside, the investigators sift through the murders, suicides, robberies and violent crimes that threaten the streets of Vegas, on and off the Strip, moving beyond the neon to this desert town’s darkest and deadliest corners. Under Grissom’s watchful eye, the CSI team uses both cutting-edge scientific methods and old-fashioned savvy to solve their crimes, driven to succeed by the pact they have made with the public they serve – “Let no victim say we did not try.”
