'We need to fight for what is right. And equal pay for women is right.' The year is 1968. Rita O'Grady and her friends work as machinists at the Ford car factory in Dagenham. It is detailed work, carried out in hot, noisy conditions. So why are the women paid the same as unskilled workers? Is it because the work is unskilled? Or is it because they are women? Rita leads a fight against the unions, Ford management and even her own family to fight for equal pay, taking the women's demands all the way to the British government.
