When a familiar face returns to Gloucester to compete for the title of top bluefin fisherman, the fleet isn't very welcoming. And for one fisherman, the ocean just isn't big enough for the two of them.

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.
