“Relentless” tells the true story of remarkable people tackling the mystery of why the fish most prized by people nearly vanished from the largest freshwater ecosystem on Earth: the Great Lakes. The crash destroyed jobs and businesses, devastating towns, tribal communities, and First Nations in Canada and the United States.

Overfishing, dam building, and industrial dumping had already decimated fish populations in parts of the Great Lakes but fish began disappearing far from industrial cities. Scientists discovered what proved to be the most destructive marine species to ever invade the Great Lakes. Their tenacious search for a way to control it continues to influence the Great Lakes region’s economic fortunes and sounds a warning about the future of natural resources and the prosperity.

The Great Lakes Fishery Commission underwrote the film’s production and is excited to share this award-winning documentary far and wide.
