Three best friends and dedicated roleplayers take to the woods to reenact a dungeons and dragons-like scenario as a live action role-playing game. Trouble arises when a prop spellbook purchased from the internet ends up being a genuine grimoire and they unwittingly conjure up a blood-lusting succubus from hell.

After a catastrophe destroys most of humanity, recluse Del lives in his small, empty town, content with the utopia he has methodically created for himself, until an interloper, young Grace, disrupts his solitude.
