When true crime podcaster Mercy St. Claire's best friend Alice gets kidnapped, it plunges her into the terrible realities of cold cases in a broken America. She turns to her beloved professor, retired criminalist Mark Thoreau, to try and find Alice, but grief, passion, and a descending darkness of terrible truths push them to take comfort in each other while killers go free. Nobody has answers. Mercy and Mark are determined to get those answers...but justice has a cost.
