Still grieving his toddler's death, Detective Dan Brennan of the Philadelphia P.D. returns to the force and is assigned to investigate a socialite's fatal fall down her mansion's staircase. But the open-and-shut case is turned on its head when the victim's daughter alleges her mother was murdered. Her evidence? The dead. The vintage photographs of past murder victims displayed on the mansion's walls have told her so.
Compelled to listen to the reclusive teen's pleas, Brennan begins to investigate her mother's death and the disturbing secrets hidden in that house. Each vintage photograph is tied to a quartet of cold cases with a disturbing commonality. As the wealthy family's long, sordid history threatens to bury Brennan, he realizes he has to make a choice: save his career, or risk it all for the chance to hear his daughter's voice again.
