This is a story about finding Xiao Mei.

Xiao Mei is missing. The interviews and memories of nine individuals who all had connections with her gradually piece together the puzzles of her life. None of them knows where Xiao Mei has gone, but all they want is for her to be all right, so everything will be all right.

Featuring the unique voice of HUANG Hsin-Yao, director of critically acclaimed THE GREAT BUDDHA+, XIAO MEI offers a glimpse of a wandering girl’s troubled life.
