Fresh off solving a series of grisly murders, Casey and Deputy Will Anders get stranded in a blizzard while they're tracking a runner from the town. Seeking shelter in a cave, they stumble across a woman who's been imprisoned in a deep well. Was she taken by one of the hostiles who inhabit the wilderness around the town? Or is Casey facing something even worse? In a town where everyone lies about their past and lives under assumed identities, it's very easy to hide your true nature.
