Wicked Tuna follows a group of salty fishermen from the nation's oldest seaport, Gloucester, Massachusetts, as they make their living the way it's been done for centuries—rod and reel fishing, one catch at a time—all in pursuit of the bluefin tuna. One "monstah" bluefin can be worth more than $20,000, and with that kind of money on the line, every captain is fighting to be the best in the fleet.
