Welcome to Millbridge, Arizona—a town built on the fortunes of the Mumford family, now facing the slow decline of its once-thriving mine. Dr. Peter Mumford, the town's beloved physician, struggles to maintain a semblance of normalcy as he carries the weight of his family’s dark secrets. As Peter goes about his day, we’re introduced to the deep ties that bind the Mumfords to Millbridge and the powerful, yet decaying, influence they hold over the town. But when a determined reporter starts digging into the suspicious deaths of 30 miners from years ago, Peter realizes that the shadows of his family's past are far from buried. The episode sets the stage for the unraveling of a chilling mystery that threatens to expose the truth—and destroy everything Peter has worked to protect.
