Plot Synopsis

CSI: VEGAS, the sequel to CSI: CRIME SCENE INVESTIGATION, opens a brand-new chapter in Las Vegas -- the city where it all began. Facing an existential threat that could bring down the entire Crime Lab and release thousands of convicted killers back onto the neon-lit streets of Vegas, a brilliant new team of investigators led by Maxine Roby must enlist the help of old friends, Gil Grissom, Sara Sidle and David Hodges. This combined force deploys the latest forensic techniques to do what they do best -- follow the evidence -- in order to preserve and serve justice in Sin City. CSI: VEGAS premiered Wednesday, October 6, 2021 at 10pm ET/PT on CBS.

The CSIs investigate the murder of a dominatrix found near her secret sex dungeon. After a three-week break, CSI: VEGAS returned with new episodes on Thursday, January 5, 2023 at 10pm ET/PT on CBS.
