A profound but light-hearted exploration of contemporary eco-activism on the Scottish seas, Of Fish and Foe follows brothers Kevin and John Pullar, who are struggling to sustain the family business of net fishing for wild Atlantic salmon off the coast of Scotland. Watching their every move, animal activist groups Sea Shepherd and Hunt Saboteurs oppose the Pullars at every turn, and frustrations frequently boil over in this thought-provoking documentary that puts modern environmentalism under the microscope.
