CSI: Crime Scene Investigation Season 10 Episodes

23 Episodes 2009 - 2010

The tenth season begins with one of the most bizarre openings in its history. The CSIs are seen frozen in time, some in midair, inside the lab, which is in disarray with corpses scattered about. A couple of lab techs appear to be shot, and Ray (Laurence Fishburne), apparently, is kicking a thug through a glass wall. Flash backward 48 hours and an intriguing story unfolds that begins with the death of a starlet who perishes in a traffic accident. Back to help the understaffed CSIs (due to Lauren Lee Smith's departure from the show) is Sara Sidle (Jorja Fox). Subsequent noteworthy story lines in Fishburne's first full season at the helm include: a cop-on-cop murder investigation, a gruesome discovery at a bowling tournament and the mysterious death of a legendary comedian. The season concludes with the CSIs attempting to capture the elusive serial killer Dr. Jekyll with the help of another serial murderer, Nate Haskell (Bill Irwin).The hunt proves to be extremely dangerous, with the life of more than one CSI placed in peril.
