After ten years as an FBI profiler, Frank Black relocates from Washington to his hometown Seattle with his wife, Catherine, and their daughter, Jordan. However, a series of sexual homicides coaxes him from retirement. He offers his support to Lt. Bob Bletcher, a former colleague with Seattle's Homicide Unit, and is in turn offered the resources of the mysterious Millennium Group, a corps of former law enforcement officers. Blessed - or afflicted - with an uncanny ability enabling him to see the world through the killer's eyes, Frank must pursue the murderer through Seattle's underground scene and stop his killing spree.
