The Nez Perce is the oldest documented civilization in North America, with archaeological sites along Idaho's Salmon River dating back 16,500 years. The cornerstone of their creation story is an agreement with salmon to protect its continued existence. Produced in collaboration with the tribe, COVENANT OF THE SALMON PEOPLE is a feature-length documentary portrait of the Nez Perce exploring how their relationship to salmon has shaped the tribe's culture, history and spirituality. As dams and climate impacts threaten to bring salmon to extinction, we trace the tribe's efforts to honor their ancient agreement .
