Sitt al-Bayt (Arabic: ست البيت, Lady of the House) is a 1949 Egyptian drama film.
Nabil's mother believes Elham is an intruder to her personal life because she is more the "lady of the house" than she was.
The hatred forces Nabil's mother to try to convince her son to marry another woman, Madiha (Mona), especially after discovering that Elham might be sterile.
Her doctor tells Nabil that Elham was actually pregnant when she fell, and that she had miscarried as a result.
The mother recognizes the mistakes she has made and apologizes to Elham and asks for forgiveness.
