After a promising start to the season, bad luck strikes. Captain TJ Ott is forced to fish on a different boat after the Hot Tuna suffers a mechanical breakdown requiring immediate repairs. And Captain Tyler McLaughlin is forced to fight a giant bluefin in the dark after his generator loses power. Meanwhile, Captain Dave Marciano reaches out to an old ally to try and turn the Falcon's luck around.

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
