Guardian(2019)

Guardian chronicles the work of wildlife stewards amid sweeping legislative rollbacks of environmental protections in Canada. Part hermit, part biologist, Guardians live on boats, full-time, in one of the last pristine frontiers of the world to monitor salmon, the backbone of the ecosystem, economy, and culture along British Columbia's coast. But, in an age of science censorship and soaring resource extraction in the form of fracking for oil and natural gas, Guardians and the wildlife they have dedicated their lives to protect are now disappearing.
