As a Greek tombstone of unknown origin is discovered underneath the floorboards in an old village house in Turkey, an almost forgotten story from the country’s creation unravels; the forced population exchange between Greece and Turkey in 1923. The engraved Cyrillic letters tell of a woman, Chrysoula Rodaki, who died in 1887. And so the search for her descendants begins: It leads director Kerem Soyyilmaz to local archives, where his own family's role in history is laid bare; to abandoned ghost towns and through the memories of older villagers - all while Soyyilmaz meets massive support for his quest from Greeks on the other side of the border. The stone becomes a portal to the past - and for a while, the trauma becomes redeemed when the previous owners of the village house return.
