Even if you've read the news coverage about the effects of farmed salmon on B.C. wild salmon stocks, the strength of Twyla Roscovich's documentary is not only how it amalgamates information about this contentious subject but also how it showcases biologist Alexandra Morton's incredible tenacity and devotion. It's as disturbing to see the visual evidence of dead and dying salmon—the keystone species essential to West Coast ecosystems—as much as it is to hear about attempts by federal government officials (who declined interviews) to muzzle and punish scientists (thereby also affecting journalists) who are trying to prove what is killing them. Also, if you chow down on salmon sashimi, this is one you'll want to see before you take your next bite.
