Wednesdays at 22:00 KSA on SHOWSERIES

The season begins on a dark note as a fellow investigator has been gunned down, and the team sets off to find the killer. The deaths just keep on coming and the CSI Vegas team hires two more investigators to help them get to the bottom of the matter.

The CSIs sift through the murders, suicides, robberies and violent crimes that threaten the streets of Vegas, on and off the Strip, moving beyond the neon decadence to the seediest and deadliest corners of the infamous city in the desert. Under Grissom's watchful eye, the 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 the evidence bring justice to the victims and closure to the survivors."

With new faces to watch including Hollywood legend Laurence Fishburne, even more unusual deaths and intricate plots linked to these mysteries, it is no wonder millions love this series that is in its ninth season.
