When a grieving mother spots a child at a mall that she thinks could be her dead son, can a skeptical PI help her find the truth?

For three years, Kate Marshall has been mourning the loss of her husband and four-year-old son in a tragic accident. But when she spots a familiar-looking child on a mall escalator, she’s convinced he’s her son.

With police skeptical of her story, she turns to private investigator Connor Sullivan for help. As the former Secret Service agent digs into the case, the “accident” begins to look increasingly suspicious. But if Kate’s son is alive, someone is intent on keeping him hidden—and may be willing to go to lethal lengths to protect a sinister secret.
