Grissom's gone and the team moves on -- and ET has your sneak peek!

The CSI team faces a forensics nightmare when they are called to the scene at a fast food restaurant on Thursday night's episode of "CSI: Crime Scene Investigation."

Langston (Laurence Fishburne) and Nick (George Eads) are the CSIs on call when a dead body is discovered at a restaurant -- and find out that most of the evidence is coated in cooking oil.

"CSI" airs Thursdays at 9 p.m. on CBS.
