Cold Case stars Kathryn Morris as Lilly Rush, the lone female detective in the Philadelphia homicide squad who finds her calling when she's assigned to "cold cases" -- crimes that have never been solved. Previously, she used her instinctive understanding of the criminal mind on current murders. Now, she's interrogating witnesses whose lives and circumstances have since changed, making use of today's new science and finding fresh clues to solve cases that were previously unsolvable, all of which appeals to this smart, driven detective. She's also prepared for the consequences: that her work will open up old wounds and may lead suspects to commit new crimes.
