Overview:In the desolate outreaches of Bristol Bay, Alaska, the most competitive fishing season on Earth takes place throughout four short weeks. 1,800 captains and their crews draw the battle lines to help save Alaska's ecosystem by reeling in a massive sockeye salmon payday. With potential fortune swimming just below the surface, five captains prepare to battle the unforgiving bay, the battering ram of boats jockeying for position and the law, which strictly monitors the season with recon choppers and police squads. On the bay, fishing for the nearly 44 million salmon is necessary for the environment, and arm of the law is long, tempers are short and every single decision is the difference between drawing a huge income and settling for pennies.
