Fisk uses ocean-current data and an old Ship's Log to predict the route of a massive bluefin tuna migration worth millions. When he demands 7 years of unpaid wages from Dylan who rules the dock, he is mocked, blacklisted, and given only a derelict boat, the Old Seagull. Refusing to quit, Fisk restores the vessel and risks everything on one voyage. Against all odds, he lands a fortune in bluefin tuna and proves his doubters wrong in a stunning comeback.
