The Edge of the Wild tells the story of a contentious land-use battle in a small Californian town that is home to a very rare butterfly, and of how this struggle has affected environmental policy across the country.

The tranquil wilderness that surrounds the town of Brisbane, California is deceptively peaceful, as the town's political battles have reverberated far beyond its borders, altering the future of endangered ecosystems across the country. The Edge of the Wild, a feature-length documentary, follows lifelong Brisbane resident Michele Salmon as she and her neighbors encounter the global endangered species crisis in their hometown, and become embroiled in a race against time to save the last of an imperiled species.
