The black kite, generally referred to as 'the eagle' in Taiwan, has become so rare that few people ever see it. Shen Zhen-Zhong, nick-named 'Mr. Kite', vows to safeguard this endangered bird and spends twenty years traveling throughout Taiwan to find out why the black kite is disappearing. From 1992 to 2015, documentary filmmaker Liang Chieh-Te followed Mr. Kite's journey.
