CSI has returned to its roots and reminded fans that it all started in Las Vegas. The original CSI: Crime Scene Investigation tackled crime in Sin City and now CSI: Vegas is returning to the mothership.

"From time to time, you will roll up on us! I know the passion people have for Las Vegas and also for CSI, so pairing the two together again... score," Paula Newsome said.

"We're going to go to a swingers club. We're going to see some nice cars. That's the beauty of Vegas. Everyone and anyone goes there, so it can just go on and on and on," Mandeep Dhillon said.

CSI: Vegas airs Wednesday nights on CBS.
