Dean Winchester is a private investigator working what should be an open-and-shut vandalism case on an isolated stretch of rural highway.

Except it’s not an open-and-shut case, because whatever is happening on Highway 9 isn’t vandalism — it’s something far more sinister and unnatural. And if Dean is going to get to the bottom of this case, he’s going to have to rely on the one person he’s learned he can’t rely on for anything — his ex-best friend, Cas Novak.
