On the first weekend of the tuna season, six charter boat skippers compete in some the toughest fishing conditions for their chance to win the Portland Tuna Cup.
Communication between deckhands and skippers becomes key as the charter boats come across big schools of tuna. Rivalries are stoked when two charter boats are both hunting the same school of fish.
The pressure mounts as big swells affect the charter boats and their clients differently. Some skippers pull ahead, but may struggle to keep the lead as the weather and competition intensify.
Facing worsening weather conditions, one charter boat faces a hard decision about whether to head home as their clients become increasingly seasick.
With one boat already out of the competition, the five remaining charter boat skippers battle it out with the harsh weather and finicky tuna to see who will come out on top.
With only three boats left in the competition, rods are bending and time is running out. Finally, the competition concludes and a winner is crowned.
