The discovery of mysterious fishing charts on the Cornelia Maria leads co-captains Josh Harris and Casey McManus to Hawaii to learn what Josh's late father, Captain Phil Harris, was attempting to accomplish decades ago.
 

Josh and his crew get an opportunity to supply ahi and mahi to a local restaurant and hope Phil's notes will lead them to a big payday. It's their first chance to turn a profit but if they want to succeed, they must first learn the Hawaiian way.
