Alaska: Battle on the Bay closely follows five captains and their ships during the annual migration of more than 44 million sockeye salmon in Alaska's Bristol Bay. 1,800 boats in the Bay must fight the elements and each other within highly policed areas of water "districts" during a tight four-week fishing season. 

It's environmentally necessary to fish for almost half a billion salmon which would otherwise wreak havoc on Alaska's waterways. Police presence does nothing to deter fishing boats from becoming battering rams and crashing into one another for prime position. With potential fortune swimming just below the surface, the crews know the unpredictable and dangerous bay is the least of their worries.
