Sarah Masters is having a bad time. After completing her first job as a courier of occult and magical objects, her car breaks down outside of the small mountain town of Halcyon, CO. What at first appears to be just another fading community turns out to be so much more sinister. Between Mysterious sigils, people disappearing without a trace, and dreams that seem to taunt her with memories from her past, Sarah wouldn't even be able to escape even if the roads weren't closed. With nowhere to run, she has no choice but to confront the danger around her.
