Midsommar Madness (S01E06)

As the adults gather for a euchre tournament at the Boathouse, Billie, Killian, and the Quads opt to entertain themselves with a Ouija board during the rainy afternoon. However, things take a strange turn when Olive goes missing, and cultists armed with crossbows show up. With the Quads lacking any semblance of common sense, it's up to Billie’s expertise in horror movies to guide the teens through this terrifying ordeal.
