Based on the Emmy Award-winning TV series, this edge-of-your-seat thriller follows the savvy and remarkable team of forensic investigators led by veteran Gil Grissom as they use the latest cutting-edge technology to track down a mysterious killer from the past. Ten years ago, Las Vegas was terrorized by a vicious and bloodthirsty serial killer responsible for nearly half a dozen brutal murders. But after two years of keeping the city in a panic, the killer mysteriously vanished and has not been heard from…until now.

Gil Grissom and his CSI team are called in to investigate a homicide that perfectly fits the notorious criminal’s modus operandi. But all hell breaks loose when a reporter made famous by the original cases receives a letter from someone claiming to be the very same killer–but he insists that he had nothing to do with the latest slaying.

Now the CSI team must stop someone who may be a copycat killer from striking again, even as a murderer from the past continues to evade capture, and isn’t taking too kindly to rivals.
