The "monsters" referenced in the title of this Discovery Channel series are bluefin tuna in the North Atlantic, and every fall, fishermen abandon their lobster-catching jobs for six weeks to pursue the most valuable fish in the sea. The series takes viewers inside the intense world of fishing for the elusive predator, which can measure up to 15 feet long, weigh 1,500 pounds and fetch more than $10,000 apiece. Each fisherman is allowed just one tag -- one chance to hit the jackpot -- a provision that helps keep the bluefin population healthy for generations to come.
