Part campy musical, part horror film, the movie details the travails of a squeaky clean couple stranded at a creepy castle where the inhabitants sing and dance through a bacchanalian romp of murder, bisexuality and cannibalism.

After a proposed pipeline creates divisions within the small town of Beaverfield, and a snowstorm traps its residents together inside the local inn, newly arrived forest ranger FINN (Sam Richardson) and postal worker CECILY (Milana Vayntrub) must try to keep the peace and uncover the truth behind a mysterious creature that has begun terrorizing the community.
