In the middle of the night, Abigail Pearson is awakened by the sound of footfalls and someone calling her name. When she goes to investigate, she sees her husband-a man who disappeared without a trace thirty years ago. The next morning, her daughter finds Abigail unconscious on the stairway landing and she is rushed to the hospital. JoAnna, Abigail's daughter engages Emily Charters to stay with Abigail after she is released from the hospital. Emily quickly comes to believe that something nefarious is at work and calls upon her friend, Jeremy Ransom, a Chicago police detective, to help her sort things out. The building tension between members of the family, and more nocturnal visits by Abigail's husband, plus the mystery of his disappearance make this the strangest case yet for both Jeremy and Emily.
