Mud features photos, videos and interviews that unearth the extensive human rights violations caused by the gross negligence of the Samarco mining company in Brazil. On November 5, 2015, a Samarco-built dam collapsed, and toxic mining waste tore through the towns of Bento Rodrigues and Paracatu de Baixo. The waste continued 300 miles down the Doce River, and emptied into the Atlantic Ocean. Towns and the Doce riverbank were destroyed. Nineteen people died, and thousands were displaced.

Today the work from this project is being used by SPG law firm in a billion-dollar lawsuit on behalf of over 200,000 Brazilian individuals and organizations, is fighting for justice, appropriate compensation for the victims and environmental restoration.
