This film tells the true story of Mrs Helen Robinson's fight with the King of the Marlins.
Mrs Robinson is 71; her ambition was to catch a giant black marlin weighing over 1,000 pounds.
She travelled from her home in Miami, Florida, to Cairns in North Queensland to begin the struggle off Australia's Great Barrier Reef. Apart from Mrs Robinson and her fishing friends Ted Smits and Vie Dunaway, the cast includes the giant marlin, the exotic and deadly butterfly cod, and Hugo the killer whale.
