The show centers on a team of forensic experts from the Las Vegas Police Department who rely on physical evidence to unravel gruesome murder cases in this particularly graphic drama. This series has sparked a wave of similar procedural cop shows. It combines elements of deduction, intense subject matter, and character-focused storytelling. The network eventually expanded the franchise with spin-offs like CSI: Miami and CSI: NY, both of which concluded after ten and nine seasons, respectively.
