Willow Springs (1973)

A feminist cult survives by robbing and killing passersby, at their remote desert ranch. The North Star Dhruva cult leader Magdalena refuses to work for the Yankee dollar. Consequently she subjugates her two followers, who are forced to listen to the music of German opera all the time, while Magdalena drinks rum and Coca Cola in the ranch's ornate bar. But the lesbian masochist's iron rule over the rundown California ranch is questioned when a mother-loving young male wanderer, Lord Invader, stops in and romances the cult's meek slave Ila, after his mother is turned away by Magdalena.
