heartless woman(1978)

Sohair returns from abroad after her husband's death and meets her mother-in-law Fatima, who gives her a cold welcome. Sohair gives birth to her child, and Fatima makes her believe that the child has died, as she wants to seize her son's inheritance with the help of the mute girl Alfat, who decides to guide Sohair to her son's location. She discovers that the woman with her in the house is not her mother-in-law Fatima, but a woman impersonating her. When she decides to reveal the matter, she finds herself locked in the house, so Alaa, her husband's cousin, tries to help her.
