Hair, Paper, Water… follows Vietnamese Cao Thị Hậu, who teaches her grandchildren the endangered Rục language, carefully passing on every word and memory. Filmed on 16 mm, the film feels homemade, with grainy images that make time tangible. The sound is essential: leaf textures, mud and dripping water create an acoustic score that activates the senses. The focus shifts from intimate observation to quiet emotion as family ties span generations. Plants, remedies and everyday actions take on meaning as memory aids. The result is a poetic, tactile family portrait in which language and culture remain alive.
