In school, the two brothers are poor students who are marginalized by others. The thin and introverted brother Ye Xichen is called a "ghost" by the people around him because of his golden left eye. The lonely and cold brother Ye Han always protects his brother from harm and injustice. Gradually, Ye Xichen found that some strange people appeared around him, and some strange things happened: a girl who loved Ye Han deeply but disappeared inexplicably in the end; the strange dream that lingered in Ye Xichen's mind during his sleep; the mysterious barber shop that only opened at dusk and closed at dawn; the monster that appeared in the school late at night; and the basketball player The boy who died strangely because of him... A series of strange and weird things filled Ye Xichen's originally plain and bitter life. In the end, all the incidents pointed at him. People around him thought he was a ghost and he killed the boy. Ye Xichen's brother Ye Han also began to doubt his younger brother. All this made Ye Xichen very desperate. Even he himself didn't know if he was really a ghost. He kept asking himself: Am I really a ghost? Am I really a ghost?
