SEASON 2, EPISODE 201 - Smart, driven Detective Lilly Rush (series star Kathryn Morris), the lone female detective in the Philadelphia homicide squad, works on "cold cases"--crimes that have never been solved. She reopens dormant, unsolved homicides that occurred years or even decades ago. Previously, Rush had used her instinctive understanding of the criminal mind to crack current murder cases. Now, this experienced detective is intrigued by new challenges, such as interrogating witnesses to old crimes whose lives and circumstances have since changed, making use of today's new science and finding fresh clues to cases once thought unsolvable. At the same time, she is prepared for certain consequences, namely that her work will open old wounds and may lead suspects to commit new crimes.
