 
 Ximen, the well-known entertainment mecca in Taipei, is also an indicator of today's young pop culture. No matter morning or night, it is always filled with all kinds of people. Tons of people come to visit, but most of them forget to see and feel the craziness, the loneliness, the love, and the color within that area. Tigger, a smart-but-lonely girl whose mother is away, comes to Ximen to start her own business. One day, she meets the maddest of them all: a homeless man called Ximen Qing, aka the Mad King of Taipei.
