Back in 1985, Camp Pocumtuck was a notroiously strict religious summer camp until it was forced to shut its doors when a young girl was struck by lightning and drowned. Before that, several women were burned at the stake for being witches nearby and before that, it was the site of a Native American massacre. Nowadays, it's avialble on Airbnb. Mia’s booked it and expects her wedding party to transform this now dilapidated summer camp into the wedding venue of her dreams. As her friends utterly fail to execute her master plan, they also begin disappearing. But nothing will stop Mia from having a perfect wedding, even when someone starts texting her to hide the bodies.
