Part of UK Green Film Festival 2026. The UK’s annual environmental film festival.

Nine years after Brazil’s worst environmental disaster, filmmaker Claudia Neubern returns to the Rio Doce. Here, a mining dam containing toxic waste collapsed, releasing poisonous sludge into the river which flows 650 km to the Atlantic Ocean. Retracing the path of the catastrophe, the film meets those whose lives, land and livelihoods were permanently transformed. Amid lasting environmental damage, local communities remain resolute, yet still powerless against a mining company that continues to shirk responsibility.

MISSING RIO DOCE is a moving portrait of wounded landscapes and the resilience of those who continue to resist.
