Just two weeks before Roya, a banned Iranian journalist, is set to emigrate from Iran to Denmark at her husband’s insistence, she encounters a quiet young girl. The girl seems lost and doesn’t remember anything. Roya takes her in, unaware that the girl has abandoned her previous life and now has come to replace Roya. A couple of days later, Roya finds out that she will be prohibited from leaving Iran unless she sells out a colleague to the government authorities. Soon after Roya refuses to betray her friend, the young girl steals Roya’s identity and takes over her life with the assistance of Roya’s husband, Babak. As Roya fights to recover her identity, she realises, to her surprise, that no one remembers her anymore and that everybody takes the lost girl to be her. Babak throws Roya out of the house, at which point the authorities decide that Roya is to be exiled to another life as a passive housewife named Hanieh.
