Captains welcome their relatives aboard. For Captain TJ Ott, having his family aboard brought success to the Hot Tuna, but can they do it again this season? And Captain Dave Marciano's nephew Jay brings a shot of new energy to the Falcon as the crew hopes to improve its performance. But on the Pinwheel, a rift between Captain Tyler Mclaughlin and his sister threatens to sink his season.

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

It's the midway point in the season, and with the pressure mounting to land a fish, the captains form alliances to increase their chances of putting meat on deck. Captains Tyler McLaughlin and Brad Krasowski hope to repeat the success of last season's alliance, but their pact is quickly tested when Tyler gets a hot tip about a new fishing spot.
