She teams up with her husband Marty to pursue a landmark appeal that challenges how the law treats men and women. Their collaboration centers on a case selected to test gender discrimination in the courts and seeks to alter a long entrenched pattern. The drama captures long hours in law libraries, cautious courtroom consultations, and the grit required to argue before judges who are wary of social upheaval. The emphasis stays on ideas, strategy, and the stubborn pursuit of equality, without revealing twists or endings for viewers. The film also highlights the cost of progress today.
