British Columbia's wild salmon population is crashing, and biologist Alexandra Morton spends the film testing fish for a cause the government seems determined not to find. Working with filmmaker Twyla Roscovich, Morton sends salmon samples to labs and gets positive results for European viruses, including infectious salmon anemia, linked to open-net salmon farms along the BC coast. The film follows her through federal laboratories and hearing rooms, using hidden and candid footage of Canadian fisheries officials discussing test results that contradict their public statements. Scientists inside government agencies describe being told to withhold or downplay findings, and samples that test positive in independent labs come back negative when the same fish pass through official channels. Morton's confrontations with bureaucrats and industry representatives form the spine of the story, tracking how a paper trail of memos and lab reports gets buried. The film treats the salmon farming industry's economic weight as the reason the science keeps getting managed rather than published, and leaves Morton still pushing for an independent inquiry by the end.
