The Sex Cycle (1967)

The Cocoa Poodle bar is the central meeting place for the denizens of a bohemian suburban area. Janet, a rather colorless model, is jealous of her artist/mentor Tanya, who attracts the attention of all the local guys. An exotic card-reader offers her a pair of earrings which will give her power over others. She soon becomes the center of attention, but commits a fatal error.
