Maryam Mirzakhani was a maths genius. She was also Iranian. Born at a time when women's rights and freedoms were being curtailed in her country, Maryam defied the odds to excel in a field traditionally dominated by men, becoming the first woman ever to win the highest award in mathematics - the prestigious Fields Medal. Tragically her brilliant career was cut short when she died of cancer at just 40 years old. This film, pays tribute to her legacy and to the talent and ambition that helped Maryam succeed.
