Moving from a small town to Tehran, Amen is optimistically planning to do gender reassignment surgery, something he has dreamed of long and hard. He meets Naser, a rich man who promises to pay for his surgery but under ever changing conditions in which the full story is never revealed. The general idea is that Amen, who has a very similar voice to Naser's daughter Annie who is about to inherit her grandmother's house, is asked to play Annie in front of the grandmother since Annie is nowhere to be found. However, Naser and many others are hiding a big truth about Annie. Using different medicines to control and change him and forcing him to stay in special conditions, they have a wicked plan. Desperate enough to become his true self, Amen goes along with the plan…but how far? At The End of Evin is about the ultimate sacrifice and how far someone might go to be who they truly are, with a decision not many of us could ever make or even understand.
