It's week nine of the North Atlantic bluefin tuna season, and Captain Paul Hebert of the troubled Kelly Ann struggles to prove his worth to his crew — and keep his job — after catching only three tuna in the first two months of fishing. Captain Tyler McLaughlin of the Pin Wheel is currently leading the fleet, but his first mate quit last week. Rival Captain Dave Carraro of FV-Tuna.com is determined to capitalize on the loss and get back into the top spot. Meanwhile, Captain Dave Marciano of Hard Merchandise is eager to take advantage of his last week with his son Joe on the boat. They'll try to catch more than one fish to establish themselves as one of the top boats in the fleet.
