Three very different, extraordinary women in Mississippi during the 1960s, who build an unlikely friendship around a secret writing project that breaks societal rules and puts them all at risk. From their improbable alliance a remarkable sisterhood emerges, instilling all of them with the courage to transcend the lines that define them, and the realization that sometimes those lines are made to be crossed-even if it means bringing everyone in town face-to-face with the changing times.
