In the early morning hours on December 23rd, 1994, Bill and Vera Loden awoke to discover fire raging through their home. Both parents desperately try to save their three small children from the flames, but the fire blocks every avenue. All too quickly, the battle ends, and the children are lost. Grieving and broken, the parents are shocked when investigators report they can find no trace of the children's remains. The relief the Lodens feel at this news is short-lived as this frightening question looms: where are their children? As the months passed, with no sightings of the children reported and no progress in the investigation, the disappearances were declared a cold case, and all of the files related to the investigation were boxed and sent to storage. Over two decades later, that dusty box remains unopened, and the fate of the Loden children remains a mystery. Riley Callen, a private investigator specializing in missing persons, receives a call from the children's mother asking for help. The case is dead-cold. The original investigation developed no leads. There isn’t even a tiny thread to pursue after so many years. Despite the impossibility of the circumstances, Riley is intrigued and takes the case. Thanks to a grateful, wealthy client, Riley has access to a remarkable technology. This tech leads her to the people she suspects kidnapped the children. What Riley soon discovers is that these people are dangerous. They have a secret to keep and are willing to do anything to protect it. What these dangerous people don't know, but will soon discover, is that Riley is dangerous, too.
