The Waning Sex on AllMovie

According to playwrights Frederic and Fanny Hatton, The Waning Sex was the male -- and this hypothesis was carried over to the film version of the Hattons' stage comedy. Norma Shearer stars as female lawyer Nina Duane, who has quite a time overcoming the chauvinist "good old boy" network in the legal system. Much to the chagrin of District Attorney Phillip Barry (Conrad Nagel), Nina manages to win an acquittal for flirtatious widow Mary Booth (May McAllister), accused of killing her husband. But our heroine's legal know-how backfires when Mary makes a play for the DA, whom Nina secretly loves. Ultimately winning out over the predatory Mary, Nina so impresses Barry that he offers to make her a full partner -- in life as well as in business.
