Emma sits down with Maggie Branson, the widow of Sheriff Hank Branson and mother of missing Sheriff Tess Branson. Through one family's heartbreak, Emma begins to understand that whatever lives beyond the West Grove doesn't simply take people.

It steals futures.

For the first time, Emma realizes that to understand what happened, she'll have to stop interviewing witnesses... and walk into the woods herself.

Emma follows the trail deeper, speaking with the physician who examined Maya after her impossible return and the deputy who witnessed events no police report could adequately explain.

Bodies that shouldn't exist.

Medical findings that defy science.

A sheriff who vanished without a trace.

The closer Emma gets to the truth, the more she begins to wonder whether she's investigating the mystery—or whether the mystery is investigating her.

Hale Mercer leaves Emma with a thumb drive containing the private files of Sheriff Hank Branson—the man who devoted his life to solving the disappearance of Maya Holloway and Jake Renner.

Inside is the sheriff's final audio recording.
