The story revolves around a young girl named Pakki in Kaliganj where all the girls are protected under strict surveillance before they are married. This results in zero freedom of their own until marriage. But before they can start their married life, they must go through a test of purity (Ganga kii Dheej). The test is to find out if the girl is pure or not and if not, she has committed some sort of impure thing or had an impure thought in her life. This is carried out by Maha Mai, who asks that the bride to be to walk 25 steps holding her hand, while underwater. Sharmi, who is Pakki's friend makes it 24 steps before she cannot hold her breath any longer. Maha Mai calls her impure and this makes Sharmi's father rage and throw a stone at Maha Mai, who in return gets Sharmi stoned as a punishment from the villagers and sent to Nark ki Dawar, where the impure girls live their entire life and her family is shamed and never spoken to again.
