Well this looks interesting... and not just in a pervy sexy way either.

Synopsis:

Day after day, Cynthia (Sidse Babett Knudsen) and Evelyn (Chiara D'Anna) act out a simple yet provocative ritual that ends with Evelyn's punishment and pleasure. As Cynthia yearns for a more conventional relationship, Evelyn's obsession with erotic spells quickly becomes an addiction that may push the relationship to a breaking point.

Dripping with eroticism and dread, THE DUKE OF BURGUNDY is a darkly decadent melodrama from Peter Strickland, the award winning writer and director of BERBERIAN SOUND STUDIO and KATALIN VARGA.
