The Heiress
The Heiress is a 1947 play that was based on the 1880 novel Washington Square by Henry James.

Catherine Sloper is a plain, painfully shy woman whose emotionally detached father makes no secret of his disappointment in her. When she meets the charming Morris Townsend, she immediately is taken by the attention that he lavishes upon her, attention she so desperately seeks from her father. Catherine falls madly in love with Morris and they plan to marry.

Catherine's father believes Morris is courting Catherine only to get her inheritance and threatens to disinherit her if she marries him. Catherine does not care, and plans to elope with Morris but not before telling him about her father's decision. On the night they are to elope, Catherine eagerly waits at home for Morris to come and take her away, but he never arrives.

Catherine is heartbroken. A few years pass and her father dies, leaving her his entire estate. Morris eventually returns, penniless. Again he professes his love for Catherine, claiming that he left her behind because he could not bear to see her destitute. Catherine pretends to forgive him and tells him she still wants to elope as they originally planned. He promises to come back that night for her, and she tells him she'll start packing her bags.

When Morris returns, Catherine takes her revenge. She calmly asks the maid to bolt the door, leaving Morris locked outside, shouting her name. Her aunt asks her how she can be so cruel, and she responds, "I have been taught by masters." The film fades out with Catherine silently ascending the stairs while Morris' despairing cries echo unanswered through the darkness.
