‘Message seen’ is a new term from the communication app that we use to communicate with our family or friends now. With ‘Message seen’ as film title, it tells a story of the relationship in a traditional Taiwan family. Li-chun is a stubborn woman with an indomitable spirit. In order to maintain her self-esteem, she suppresses her feelings and leads a competitive life for over a decade. She tries to ignore the fact that there are many family problems, and that she might well be lonely. After the accidental death of her son, Kai-wen, she puts all her expectations on her daughter, Kai-ting. Li-chun gives her everything she can, and hopes she will enter the best senior high school. But then Kai-ting lies to her − and this lie causes the family to go haywire.
