Liquid Dreams (1991)

In a slightly future America, a woman goes to the big city to visit with her sister, who is dead in her apartment. In order to find out what happened to her sister, she gets a job working at a dance club, a lower notch in the strip joint circuit. Some of her colleagues begin showing up dead as she uncovers a sinister hierarchy in the strip club management that is harnessing the sexual activity for their own twisted ends.
