This brand new CSI spin-off is actually based on the career of an Irish cyberpsychologist called Mary Aiken, who is played by Oscar winning actress Patricia Arquette in this fictional drama. She plays Special Agent Avery Ryan, head of the FBI's cyber crime division, a unit at the forefront of solving illegal activities that start in the mind, live online, and play out in the real world. They bring us straight into the thick of it too with their first assignment involving a case of hacked baby monitors. James Van Der Beek aka Dawson Leery co-stars as Agent Elijah Mundo.
