In 15th century Austria, goatherd Albrun begins to gradually discover an ancient and malevolent presence deep within the remote Austrian Alps after the mysterious and horrifying demise of her mother. At a time when pagan beliefs about witchcraft and feminine wickedness spread fear into the minds of rural folk, the traumatized Albrun's reality evolves into a waking nightmare when she becomes a mother herself. Haunting and stylishly directed by debut filmmaker Lukas Feigelfeld, with an unsettling and immersive industrial score by MMMD, Hagazussa is a dark tale of a woman's struggle with evil and her own sanity that explores the thin line between ancient beliefs, black magic, and delusional psychosis.
