Green Blood is the result of a collaborative investigation into the practices of three mining companies operating in Tanzania, India and Guatemala. During eight months, forty journalists from fifteen countries have continued the work of local journalists that has been threaten, jailed or killed as the result of their investigation into the environmental cost and rapid expansion of the mines.

This documentary is a behind-the-scenes account of this incredible collaboration.

An African journalist wishing to remain anonymous joined the Green Blood project to investigate dozens of cases of violence and murders committed by the guards of a gold mine in Tanzania. Local journalists who have worked on the subject have been threatened, censored and sometimes forced into exile. The reporters working on the project confront the Tanzanian government with these crimes, committed in the mine, which have never been prosecuted. In Guatemala, journalists are trying to measure the contamination around the nickel mine. Local people complain about respiratory problems and skin di seases. In India, journalists collect unpublished witnesses’ testimonies to the attack on Jagendra Singh. Four years after the journalist’s death, the case will come to a twist.
