Madame X - An Absolute Ruler (1978)

The notorious pirate ruler Madame X places a print ad, calling on women to escape their boring lives and promising "gold, love and adventure" to all who come aboard her ship, the Orlando. A motley crew including a housewife, diva and artist (played by Yvonne Rainer) embark on a quest for self-transformation, which quickly heads towards destruction as they are subjected to Madame X's sadistic, erotic escapades.
