Depraved Prince Prospero throws a decadent ball while a plague wreaks devastation across his lands.

In mediaeval Europe, Satanist Prospero has power absolute over local peasantry and nobility as the plague sweeps the country.

Abducting Francesca from her village, he hands her to his jealous consort Juliana to be tutored. Prospero taunts Francesca for her morality, pushing Juliana to complete her initiation into Satanism in a psychedelic dream sequence.

Plus two shorts- The Pit, The Pendulum and Hope by the fantastic Jan Svankmajer and The Tell Tale Heart by Ted Parmlee.
