When Pak Tin Estate is going to be demolished, the residents will move to a new place, but how about the dead residents? Where could they go? Ho Ying-kuen who majors in Myth and Poetry, and Playwriting, leads us to a time and space of a demolishing public estate. We will come across the residents of the estate, a mother with her two sons selling incenses, and two monkeys having conversation about their mother. A mixture of fiction, experimental and documentary images, Lost Cemeteries studies about filial piety and death with a strange and interesting approach.
