The story takes place in a small town in the south of the Yangtze River in the old society in the 1930s. Capitalist exploitation ruthlessly impacted the originally fragile local economy, and the town that had been peaceful and quiet was also deeply affected by the whirlpool of the times. The protagonist Nannan lived in such a turbulent situation. He was unwilling to believe that his mother had left him. He told everyone that his mother had promised to come back to pick him up. After being ridiculed by his friends, he began to use his own actions to find his dream mother. Ink animation has always been one of the most representative forms of animation in China, but in recent years, ink animation has gradually declined due to its cumbersome craftsmanship and high difficulty in production. The purpose of this film is to use this unique expression method of domestic animation, use the "quiet and vivid" method in traditional culture, and use the tranquil pictures of the traditional Chinese Jiangnan water village style to set off the turbulent changes in the entire era background. Through a small person and a small story, it shows the suffering of ordinary people in the torrent of history and cherishes the hard-won good life now.
