The Lake - Season 1 Episode 6
Midsommar Madness

While the adults are at the Boathouse euchre tournament, Billie, Killian, and the Quads decide to pass the rainy afternoon with a Ouija board. Things get weird quick with the disappearance of Olive and the appearance of crossbow-wielding cultists. With a serious lack of common sense among the remaining Quads, it’s down to Billie’s horror movie knowledge to get the teens through this nightmare.
