In an apartment building in Taipei, a high school girl—the only child in the family on the top floor—leaves home after being grounded for several days. As for the DINK couple in the middle, the husband is going on a business trip but also rushing to his ex-girlfriend who came from the US. Down to the big family with four children on the first floor, the father cannot bear the noises anymore and announces first thing in the morning that he will work overtime today. This is a new middle-class cosmopolitan comedy shaped by multiple narratives.
