Harpoon Hunters

Four harpooners chase some of the world's highest-priced fish using only fast boats and expert aim. Niko must prove he can run a legendary boat while Joe hunts to support his family as the fleet races to land the first monster bluefin worth thousands.

Captains Joe and Tyler hit bluefin gold as second-generation harpooner Niko Chaprales fails to land even one. Feeling pressure to live up to his famous father's legacy, strongman Niko changes tactics in hopes of earning a big first payday of the season.

Captain Joe Dion takes his sons to sea, landing two massive bluefin and witnessing a great white shark feeding on a humpback whale. Dylan's son Emmett earns his first harpoon attempt while Niko hunts the season's biggest bluefin thus far, worth $10,000.

As the fleet spots the first giants, Joe fights for his lead over Niko & Tyler but all bets are off as old-timer Bill joins the derby. Emmett struggles with the choice to fish without a plane. When Dylan gets a $6K tuna, holding onto it is another matter.

As the bluefin fishery reaches its mid-season peak, three centuries-old fishing strategies compete for dominance. Joe banks on instinct, Tyler uses science to gain the upper hand, and strongman Niko relies on legacy -- but nobody relies solely on luck.

With the advantage of spotter planes, veteran Tyler and young gun Joe battle for the most monster bluefin until Joe helps strongman Niko get back into contention. But when Niko's zapper fails at the worst possible moment, Tyler steps in to save the day.
