Cao Thị Hậu and her family live in Vietnam, surrounded by rolling green hills enveloped in mist. Here she sits with her grandchildren tending to their pains and spinning stories of the cave in Quảng Bình where she was born. Folk tales, bees, tigers, and home remedies all braid themselves into her fables and the wisdom she imparts. As a storyteller and one of the few remaining indigenous Rục people, Hậu is the keeper of memories and knowledge. She is the steward of a fast-disappearing language, and it is her duty to fill the lives of her descendants with her words as she prepares to answer that last call from the faraway cave. Using Bolex cameras and a lush sound design, filmmakers Nicolas Graux and Trương Minh Quý deliver a visual treat along with an invitation to enter Hậu’s extraordinary world.
