A missing student. A mysterious school. And one man's search for the truth.

Former FBI agent Ryan Walker is a private investigator who tracks down people for the wealthy and powerful, frequently crossing the line between justice and revenge. Disgraced by his final operation as an agent and haunted by the demons of his past, he is now lost in the world of missing persons.

Walker seeks atonement for his sins when a client calls upon him to find his missing daughter who vanished from her prestigious private school in suburban Washington, D.C. without a trace. But as he delves deeper into the mystery surrounding the girl's disappearance, he unexpectedly enters a hidden world of secrets, lies, and deception.

Realizing the elite academy is not what it appears beneath its resplendent surface and driven by a desperate quest for redemption, Walker will risk everything -- whatever the cost -- to uncover the truth of what really happened at the shadowy school they call...the gilded sanctum.
