Women in Revolt.

Candy is an aloof heiress caught in an unhappy relationship with her brother. Jackie is a virginal intellectual who believes women are oppressed in contemporary American society. And Holly is a nymphomaniac who has come to loathe men, despite her attraction to them. Together, they join a militant feminist group, P.I.G. (Politically Involved Girls), but their newfound liberation doesn't make them any happier.
