Tiener Qin Li werd op school geboycot en gepest omdat zijn vader een overval had gepleegd. Toch stond de transferstudent Huang Shu, samen met zijn vrienden Wang Di en Feng Xuejiao, stevig aan zijn zijde, en met z'n vieren vormden ze een hechte vriendschap. De dingen die tijdens hun jeugd gebeurden, bleven hun relatie echter op de proef stellen. Elkaar steunen of verraden? Wat zouden ze kiezen om te doen?
