Inspired by the powerful true story of a young Ruth Bader Ginsburg (Academy Award® nominee Felicity Jones), On the Basis of Sex depicts a then-struggling attorney and new mother facing adversity in her fight for equal rights. When Ruth takes on a ground-breaking case, she knows the outcome could alter the courts' view of gender discrimination. Stronger together, Ruth teams up with her husband, Martin Ginsburg (Armie Hammer), to fight the case that catapults her into one of the most important public figures of our time.
