A cancelled star. A cursed camp. And a killer who doesn't care if you're trending… Cancelled after a drunken, ill-advised post, TV-star Willow McKenzie is sent to Camp Castaway - a retreat in the woods where you hide from your mistakes. Spoiler #1: there's nowhere to hide. That first night, fellow campers gather round a fire, telling ghost stories. And Willow hears the tale of Knock-Knock Nancy - a beheaded local woman whose spirit still roams the woods. Spoiler #2: she takes her victim's heads. Willow doesn't believe in ghosts - until next day, a camper vanishes. And, that evening, Willow hears it: Knock. Knock. Knock. Spoiler #3: It's already too late . . .
