Shawn and Gus receive a mysterious email inviting them to the Cinnamon Festival in Dual Spires, a quirky small town nearly invisible on a map. They arrive to find themselves embroiled in the mystery of the drowning death of a teenage girl -- who was declared dead under similar circumstances seven years ago in Santa Barbara. Sherilynn Fenn, Sheryl Lee, Dana Ashbrook, Robyn Lively, Lenny Von Dohlen and Catherine Coulson guest star.
