'Tis about to get medieval up in here.

Knights of Badassdom (2014)

Directed by Joe Lynch

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.
