The deeper they dig, the darker it gets.

A new string of murders—each echoing a familiar, haunting pattern—forces Agent Adams to confront the chilling possibility: the case isn’t over. As she fights to untangle the truth, she realizes they’re all connected. But how far will she go for justice—and what will it cost her?

The focus now shifts to the mystery that has haunted the investigation from the beginning: What happened to Charlotte Mercer? The girl who vanished without a trace many years ago. The girl who may hold the final piece of the puzzle.

With time running out and the line between hunter and hunted dangerously thin, finding her grave might be the key to unlocking everything. Or it might bury them all.

Based on true events.
