Celia Whittaker, a reclusive socialite who has long eschewed romantic opportunities, learns her younger sister Joan intends to marry David Eastman, an older author and professor, though she is truly in love with Richard, a fledgling doctor. Meeting David before learning he is her fiancée, she learns he is not fully in love with her either. Despite this circumstance, their domineering father insists on seeing the wedding go forward, to the point of attempting to have Celia confined to her home against her will. In a flashback, the roots of Celia's behavior of melancholy isolation are revealed.
