From the moment she arrives in Freiberg, Germany, to attend the
prestigious Tans Academy, American ballet-dancer Suzy Banyon (Jessica
Harper) senses that something horribly evil lurks within the walls of
the age-old institution. Ill at ease as the result of her fellow
student's peculiar behavior and increasingly terrified following a
series of gruesome and spectacular murders, Suzy slowly begins to
unravel the dark history of the academy. Convinced that the occult roots
of the school and the horrific tale of its founding mother may hold an
unthinkable secret, she begins a hallucinatory journey into the black
heart of one of the most powerful witches ever known to exist. As Suzy
edges ever closer to a secret that may hold the answers to all of her
nightmares, the coven's grip on her soul begins to tighten until there
is seemingly no escape. Will Suzy solve the mystery of the cursed
academy before the fearsome Black Queen consumes her, or will she
finally reveal the secret that has forever haunted the lavish corridors
of the academy and bring an end to the Black Queen's terrifying reign?
