No one knows who the killer is, not even the cast! Mirth meets murder in the world's daftest whodunnit. CSI: Crime Scene Improvisation is an utterly unique murder mystery comedy that's different every show. A rip-roaring crime comedy entirely made up on the spot to solve a surreal murder chosen by the audience. Who? What? How? The choice is yours. The problem is theirs! A creative idea, truly funny **** (RemoteGoat.com). CSI leaves you feeling like you were part of something unique **** (Everything-Theatre.co.uk).
