Just as best-selling author Emma Larsimon announces she's done writing horror, an unnerving visit from an old friend draws her back to her hometown.

While a quirky police inspector digs into her parents' case, Emma drags Camille back to Caro's home and reconnects with the rest of her old crew.

Tonio makes a disturbing discovery at the shore. Another harrowing night with Emma pushes Camille to her limit. Marianne turns up the heat.
