It's late in the Atlantic Bluefin Tuna season. In the iconic fishing town of Gloucester, Massachusetts, many boats are done for the season. But there are two crews still fighting to land monster tuna and keep their family businesses going through the winter. As the weather worsens, the fish get bigger and the stakes get higher. These monster tuna can weigh more than 1,000 pounds and are reeled in the old fashion way – by hand – making it the ultimate battle of man versus beast. In an all new Discovery Channel series, All on the Line, it's all hands-on deck as these fishermen risk everything to bring home a monster payday.
