Meet the little-known & even less understood heroes of police work in Las Vegas - the forensic investigators.

What happens when a reality TV series gets a true dose of reality? A staged prank for a hit scare show has gone horribly wrong with an actor now dead and production halted indefinitely. As the graveyard shift of Sin City’s best crime scene investigators—including Catherine Willows, Ray Langston, Nick Stokes, Sara Sidle, and Greg Sanders— digs deeper behind the scenes, more questions than answers pile up: Was the botched prank’s set-up simply a case of carelessness on the producers’ part resulting in a tragic accident, or did someone really orchestrate an elaborate scheme for revenge and murder?

A retired judge has been found brutally murdered on the outskirts of Las Vegas, complete with a macabre yet masterfully intricate tattoo on his face . . . the third seemingly random victim of the mysterious kidnapper dubbed by law enforcement as the “Tattoo Man.” The judge wasn’t the first person to have been abducted, drugged, and permanently altered with tattoos and body modification . . . but he was the first to wind up dead. At the same time, several other deceased are turning up all over Sin City with their body art mercilessly removed—and the timing would seem to suggest to those in authority that all of these crimes are somehow related. But Las Vegas’s top crime scene investigators—Catherine Willows, Ray Langston, Nick Stokes, Sara Sidle, and Greg Sanders—aren’t jumping to any conclusions, as they attempt to connect the dots by entering the secretive and tight-knit body art community—one that is intensely wary of outsiders. . . .

A package with no return address is delivered to the University of Nevada's anthropology department, and a genuine shrunken head is inside. At first, Gil Grissom and his team consider it a grisly relic, but soon evidence points out that it is, in fact, a modern-day murder. Original.
