Taiwanese girls’ school students are practicing hard for the visit of the Shanghai sister school delegation. The intense practice for the performance of the honor guard holding the national flag will be held as the finale of the reception. The problem arises when the honor guard event, where the national flags of China and Taiwan are raised, is suddenly canceled due to Cross-Strait relations. On the surface, the film portrays a cheerful youth club movie. When the special diplomatic issue between the two sides of the silent war becomes tense by the national flag issue, the girls present a silent performance without guns and flags. [SONG Hyojoung]
