In a city where crime never sleeps, only the leading crime scene investigation group in the city dares to bring the guilty to its knees. The clues are gathered and examined, the trails are found and followed. When the dust finally settles, justice will always claim its due.

After the success of its originator CSI and its first spin-off series CSI: Miami comes probably the most controversial CSI of them all. Set in New York City where crime is already becoming synonymous with everyday life and murder has become all too common, the city's crack Crime Scene Investigation unit steps up to the task to root out the culprit and prevent yet another death from being just another population hiccup.

The crime rate just tripled... but so did the evidence.
