It started as a joke: a couple of backpackers upload a YouTube video about their stay in a supposedly haunted house...

But then, things turn bad.

Dylan Lee, with a major in film, is documenting his backpacking holiday with his friend Amy in a series of YouTube videos.

Their trip is fairly uneventful, and only a handful of friends are following their adventures... until their car breaks down and they accept an offer of a few week's accommodation in an old gamekeeper's cottage in the grounds of Moreton Manor.

Dylan suggests that they do a tour of the decrepit old cottage and ham up the suspense for YouTube. They upload it and go to sleep...only to be woken in the night by an unearthly scream.

It's probably a fox, Amy tells viewers.

But when someone spots a strange column of light picked up by the camera, their friends share the video... and it goes viral.

Warnings to leave pepper the comments from locals, but others gleefully urge them to stay.

As the days go on, and the ghost becomes more vengeful, Amy's fear grows. She wants to leave, but with millions of eyes on his nightly YouTube updates, Dylan is certain that this will make his career.

He's staying, no matter what.
