Three fly fishermen (Conway Bowman, Kirk Deeter and Chris Santella) head up to Kodiak Island, Alaska to fish a legendary river that’s a bit like a unicorn – everyone has heard about it, but no one seems to have seen it, been there or fished its shallow waters. Along with local guide, Trent Deeter, the crew embarks on one of the most epic and prolific steelhead fishing trips of their lives.
