A chilling slasher from a razor-sharp new horror voice, perfect for fans of Grady Hendrix and the Scream franchise

When Willow posts something on the internet she really shouldn't have, she flees to Camp Castaway, an adults-only digital detox based at an old campground in the woods.

On the first night, the campers gather round the fire to tell ghost stories. In particular, the tale of Knock Knock Nancy - a witch, supposedly beheaded in this very woodland.

They say her restless spirit knocks on doors late at night. If you answer, she'll take your head.

Willow doesn't believe in ghosts. But next morning, a camper has vanished. And then that evening, alone in her cabin, Willow hears it...

Knock, Knock, Knock.
