For a sleepless city like Taipei, the lives of the rich and poor occasionally cross. These people flit in and out of one another lives, in a seemingly endless food chain of love.

On his 60th birthday, Van is told that he is seriously ill. But instead of going to Taipei for treatment, his illness leads him to Japan. Together with his son, he goes in search of the father who abandoned him 50 years ago. At the same time, a young man with a mysterious connection to Van's past is travelling from Hong Kong to Taiwan.
