Ember in the Land of Nothingness.

At first glance, Grandma Mui and Uncle Cheung look just like another ordinary elderly couple loitering outside a school wall. Grandma Mui is suffering from Alzheimer’s disease and her conditions deteriorate notably after the death of her granddaughter Ka-ching from a fall off the school building, with the school officials suspected of negligence and being dishonest in their testimony. Stricken by grief, Grandma Mui’s mind falls into complete chaos as memories, delusions and reality mesh together. Uncle Cheung, indirectly connected to Ka-ching’s death, lacks the courage to tell the truth. As an act of atonement, he takes care of Grandma Mui even when the future looks bleak.
