The first five minutes of this new documentary extol the virtues, the beauty, the rarity, and the environmental and ecosystem value of the salmon spawning in Bristol Bay, in the southwest corner of Alaska. The remaining 55 minutes reveal the dangers posed by an international consortium that has purchased mineral rights to 330 miles of state land, and plans to extract silver, gold and other minerals in a mining operation that could threaten, if not destroy, the natural system in the region.
