In a lost-and-found tale that soars far beyond just a happy ending, Taiwanese fine artist Belle Yang pays affectionate homage to the city of Beijing.

In busy Beijing, New Year’s Eve firecrackers scare a stray white cat into the courtyard of a young girl. The two become fast friends, riding the girl’s bike through the city and seeing all kinds of people and things. Trrrring-trrrring! the girl chimes with her bicycle bell. Niaow-niaow! answers Kitty. On the day of the Dragon Boat Festival, the girl and the cat watch the kites soaring above crowded, chaotic Tiananmen Square. Kitty is enthralled by the enormous, colorful dragon kite, and she leaps to catch it as it sails up into the sky — taking Kitty with it and carrying her out of sight! The girl searches the city, visiting all their favorite spots and ringing her bell along the way, but Kitty is nowhere to be found. Will the two ever be reunited? Or could another unexpected friendship be in store — for both of them?
