Cold Case plot
Lilly is a passionate detective who made her mark with the Philadelphia Homicide Division. The transfer to 'cold cases' is a turning point in her career for Lilly. From then on, she has to start questioning witnesses from murder cases, sometimes twenty-five years ago. Using old evidence, new interrogations and current technologies, Lilly digs into the past. She is assisted in this by her mentor Lt. Tom Stillman and her somewhat arrogant colleague Detective Scott Valens. She has set herself one mission; no victim should ever be forgotten.
