The show: Stray fibers found on a victim's body, the composition of the dirt around it, bullet holes in a nearby wall and other physical evidence left at a crime scene tell a story. The forensic investigators in "CSI: Crime Scene Investigation" use the power of science to connect the dots and reveal the criminal narrative for the Las Vegas Police Department.
The spinoffs: "CSI: Miami" follows forensic investigators and police officers of the Miami-Dade Police Department, who, like their Las Vegas counterparts, use scientific methods to help solve crimes. "CSI: NY" follows the equivalent investigative team from the NYPD.
