The Age of Innocence (1993)

Society scion Newland Archer is engaged to May Welland, but his well-ordered life is upset when he meets May's unconventional cousin, the Countess Olenska. At first, Newland becomes a defender of the Countess, whose separation from her abusive husband makes her a social outcast in the restrictive high society of late-19th Century New York, but he finds in her a kindred spirit and they fall in love.
