Mean Amazon Bitches 4 (2011)

Nick Broomfield and a documentary crew visit Pandora's Box, an up-scale house of bondage on Manhattan's Fifth Avenue, where clients pay $175 an hour to be subservient to mistresses. Mistresses talk about their craft; a few clients, usually masked, are interviewed as well. Then, the camera watches sessions organized around fetishes: rubber, wrestling, corporal punishment, masochism, and infantilism. Mistress Raven, the owner of Pandora's Box, explains that pain need not be part of the subservient experience: it is, at its root, a transfer of power. After their session has ended, clients talk about how drained, relaxed, relieved, and at peace they are.
