Sze-man is facing a dilemma when she participates in an inter-school debate. On the negative side, she is working on the motto “Hong Kong Government should allow Mainlanders to settle down in Hong Kong”. During the course of preparation, however, she is constantly challenging her own position. Her “secret” as a cross-boundary student living in Shenzhen is carefully kept away from her classmates for fear that she will be discriminated against. With more and more drifters crossing the Hong Kong - China border, we are actually facing a changing time with a fast-developing and unique relationship with the Mainlanders, as well as ourselves.
