Set in 1950's New York, two women from very different backgrounds find themselves in the throes of love. A young woman in her 20's, Therese Belivet (Rooney Mara), is a clerk working in a Manhattan department store and dreaming of a more fulfilling life when she meets Carol (Cate Blanchett), an alluring woman trapped in a loveless, convenient marriage. As an immediate connection sparks between them, the innocence of their first encounter dims and their connection deepens.
