Nora Tyler returns to Alaska after many years away and finds work on a salmon fishing boat, but the long, hard season brings both deep friendships and unexpected violence.

Over the course of the long, hard season, Nora reawakens to the beauty of fishing for salmon on the outer coast. Her four crewmates have their own troubled pasts, and she forms a different bond with each one. A rivalry develops with another boat, the Viking Hero. When a woman is lost overboard from the Hero, Nora tries to understand what happened and finds that the Hero was dealing drugs and her crewmate Danny was part of the action. Toby?s ex-girlfriend, Sara, takes the place of the missing woman and finds herself in a difficult situation with no easy way out. At the end of the season, Nora and her crewmates go duck hunting on the Stikine River flats. Two of the Hero?s crew appear, perhaps not by chance, and the confrontation turns violent.
