Nader (Peyman Moadi) and Simin (Leila Hatami) are a couple, and their daughter is Teme (Sarina Farhadi). Simin hopes that the family of three will move abroad, but Nader firmly opposes it because Nader's father suffers from Alzheimer's disease and needs care. The two went to court for this and prepared to divorce, but the court rejected her request. Simin returned to her parents' home in anger. After Simin left, Nader was unable to take care of her father, so he hired a caregiver, Reitz (Sareh Bayat), to take care of her father. However, her father's toilet problem always bothered Reitz, and according to the teachings of the Koran, she felt that there were many taboos. Reitz's daughter accompanied her, which also distracted her. After several rounds, Nader returned home one day and found that his father was tied to the bed. He pushed Reitz down in anger. Unexpectedly, the pregnant Reitz had a miscarriage. Reitz's husband was furious and took Nader to court. They each insisted on their own story, but the truth was unexpected... The film won the Golden Bear Award, Best Actress and Silver Bear Awards for Best Actor at the 61st Berlin Film Festival.
