Bai Ta Zhi Guang

The Shadowless Tower | Der schattenlose Turm
Gu Wentong is a divorced food critic with a daughter whom he has arranged to be brought up by his sister. Thanks to an incident that destroyed the family, he has not had any contact with his father since he was a child. One day, he learns that his father lives alone in Beidaihe, a coastal town 300 kilometres north-east of Beijing. Still bearing a large grudge, Wentong is reluctant to visit his “disgraced” father. In the meantime, he begins a relationship with a younger colleague, the photographer Ouyang Wenhui, who is also from Beidaihe. They often meet in the area near the White Pagoda and visit local restaurants together. Wentong then begins to reconsider his roles in life as a father, son and lover.
In this romantic and enchanting film, Zhang Lu explores the possibility of recovering all the emotional and spiritual fragments that are lost during the course of our lives to prevent them from being forgotten. People come closer to each other, and move away again, but the images and sounds remain to bear witness to their passage.
