Reciprocal Sacrifice takes viewers on the journey of a salmon seeking to return to its spawning grounds in the Sawtooth Mountains. The salmon narrates the challenges it faces as it swims upstream and tells of the heating of the water in the lakes, creeks and rivers in the Snake River Basin. With voiceovers by members of the Nez Perce Tribe, viewers learn of the salmon’s generosity in sustaining people and ecosystems over generations.
