A mysterious beachcomber appears one day on the coastal bluffs near Carverville, whose best days are long behind it. Who is he, and why has he returned after nearly 40 years? Carverville's prodigal son, James, serendipitously finds work at the Eden Seaside Resort & Cottages, a gentrified motel, but soon finds his homecoming taking a sinister turn when he and a local teenager make a gruesome discovery, which forces him to reckon with the ghosts of his past—and the dangers of the present. Rumors and conspiracies spread among the townsfolk, all of them seemingly trapped in their claustrophobic and isolated world. But is there something even more sinister at work than just fear of outsiders?
