in 1998, mining waste contaminated with lead spilled into the Klity River in Kanchanaburi, western Thailand.

This documentary is about the consequences for the people of a rural village 15 years on from the contamination. They are Karen, an ethnic minority, and depend on the river for food, water and their livelihoods. The river is their only source of water. We see their lives, their children, their land. It's shown in a gentle, beautifully filmed slice of life manner which makes it quietly powerful.

There have been clean-up efforts but news reports indicate that the river is still contaminated.
