The Switchblade Sisterhood.

A young woman discovers second-wave feminism, while meeting with her estranged half-sister, as they encounter the grief, rage, jealousy and injustice that govern their lives. The academic and political discussion of women's liberation and feminism (as part of the sexual revolution of the 1970s) draws inspiration from 'The Scum Manifesto' by Valerie Solanas and juxtaposes these passage with country music from the same era; notably 'The Pill' by Loretta Lynn, 'Just Because I'm A Woman' by Dolly Parton and, most centrally, 'Stand By Your Man' by Tammy Wynette.
