It's 2021, and the Taliban have regained power in Afghanistan.

Parvana and Shauzia, the brave protagonists of The Breadwinner, must now flee to escape new dangers from an old enemy. It has been 20 years since Parvana and Shauzia had to disguise themselves as boys to support themselves and their families.

But when the Taliban were defeated in 2001, it looked as if Afghans could finally rebuild their country.

Many things have changed for Parvana since then. She has married Asif, who she met in the desert as she searched for her family when she was a child.

She runs a school for girls. She has a son, Rafi, who is about to fly to New York, where he will train to become a dancer.

While Asif tries to get Parvana's sister, Maryam, and Rafi on one of the last flights out of Kabul, the Taliban come to the school, and Parvana must lead the girls out of Green Valley and into the mountains.
