"CSI: Cyber" stars Emmy Award winner Patricia Arquette in a drama inspired by the advanced technological work of real-life CyberPsychologist Mary Aiken. Special Agent Avery Ryan (Arquette) heads the Cyber Crime Division of the FBI, a unit at the forefront of solving illegal activities that start in the mind, live online, and play out in the real world. She also knows firsthand how today's technology allows people to hide in the shadows of the Internet and commit serious crimes of global proportion. While other agents search for criminals in dark homes and alleys, Ryan searches the "dark net," a place deep in the bowels of the Web where criminals are anonymous, money is untraceable and where everything is for sale with just a keystroke.
In Season 2, D.B. Russell, a civilian specialist, transfers from Las Vegas to become the director of the newly created division of Next Generation Cyber Forensics. He joins Avery and her team as they track down the most dangerous cyber criminals, beginning with the hacking of a home security system that turns into a homicide investigation. Also, Avery considers moving to a new position within the hierarchy of the FBI, Krumitz is a witness in his sister's trial, Elijah deals with a delicate family situation and more is revealed about both Nelson's and Raven's backgrounds.
