Taking its title from a rare species of butterfly, The Duke of Burgundy chronicles the increasingly intimate relationship between wealthy amateur lepidopterist Cynthia (Sidse Babett Knudsen, of acclaimed Danish television drama Borgen) and her newly hired housekeeper, Evelyn (Berberian Sound Studio's Chiara D'Anna). As Cynthia's demands begin to betray a sadomasochistic streak, Evelyn becomes less a domestic servant than an outright sex slave, submitting to her progressively extreme humiliations with a surprising relish.
