Hayati is a small-town literature teacher and a one hit wonder author who tries helplessly to hold on to his past: his shattering marriage, his sick old mother, a decaying walnut tree and the memory of his father. Instead of moving on with his life and taking control, he passively accepts its blows and is only interested in digging into the past, until his discovery forces him to confront his own weakness and answer the question: is standing idle while witnessing evil being done is just as much of a sin as doing it?
