A screener at the British Board of Film Classification (BBFC), who has earned an unsavory reputation for being the strictest censor of violent films, begins to spiral out of control after viewing a low-budget horror with similarities to the disappearance of her sister.

The story follows Hermia Summerdream, a young woman plagued by a recurring dream of a forest she’s never visited and voices that echo in languages she doesn’t speak. As the veil between sleep and waking life begins to erode, Hermia becomes increasingly drawn to the ruins at the edge of Veronaville — ruins said to be cursed by the spirits of wronged lovers.
