A dark comedy about an ambitious director staging his theatrical masterpiece: a play based on the Gothic vampire tale "Carmilla". One night, his eccentric cast meets him at a remote and forbidding house to rehearse in the cellar that inspired the play's unfinished set. The cellar, a rumored ancient place of worship, even has its own altar! As night passes in the eerie crypt, inhibitions fade, passions burn and tempers flare; until it becomes terrifyingly clear that before this cast takes its final bow, blood will be spilled.
