An extraordinary cinematic experience, this award-winning, dialogue-free film examines heritage and cultural identity in the face of modernisation. From the salt pans to the coal mines, from the north to the south – this richly layered exploration takes us into the world of Mexico’s Indigenous population and Afro-descendent communities. Sequence after sequence shows these hardworking people as they strive to preserve traditions, trying to survive in an ever-changing world. Set to the sound of hammers on stone, the beat of tribal songs and feet shuffling across the soil as its subjects endeavour to make a living, the film invites us to bear witness to acts of determined humanity.
