The captains are challenged when a large group of boats shows up for the weekend. Hot Tuna must decide whether to risk leaving a familiar bluefin hot spot in order to climb the leaderboard. Meanwhile, FV-Tuna.com's and Pinwheel's determination to be No. 1 in a tight race to the top forces the fleet to prove they can steer in the right direction to catch bluefin and stand out from the crowd

Stormy weather hits Gloucester, and the captains must fight the elements if they want to catch a tuna. Although the rough weather presents dangerous conditions, the strong currents also stir up the ocean, making the bluefin more likely to bite. This could mean staying out for many days. With great risk comes great reward, and one captain brings in a monster payday that shakes up the leaderboard.
