In this atmospheric thriller, Brother Thomas's quiet monastic life shatters when Detective Rachel Weaver arrives at his monastery with news of murdered men—all connected to a drowning from his past. Twenty-five years ago, Thomas witnessed the death of young Jimmy Novak and did nothing to stop it. Now, as a vengeful entity wearing Rachel's face hunts the guilty parties, Thomas must confront his darkest secret. Their investigation leads to Lake Muskegan, where Jimmy's grieving mother has summoned something ancient from the depths. As supernatural forces close in, Thomas faces an impossible choice: sacrifice himself to save Rachel, or fight against a darkness that demands penance at any cost.
