SEASON 1, EPISODE 101 - Headstrong and resourceful Detective Lilly Rush (series star Kathryn Morris) works on "cold cases" for the Philadelphia Police Department, reopening 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 science and finding fresh clues to cases once thought to be unsolvable. Rush sometimes seeks advice from her mentor, Lieutenant John Stillman (series star John Finn). Also on the team is Detective Nick Vera (series star Jeremy Ratchford), a tough expert at getting confessions. Rush sees her new assignment as a turning point in her career, and she makes it her business to ensure that no victim is ever forgotten.
