The dark scales of the pacific bluefin tuna have earned them the name, "black diamonds". This is the story of the men of the sea who risk their lives to reel black diamonds in. We send a reporter and cameraman on an ocean tuna fishing boat to get full coverage of tuna fishing! Plenty of exciting shots of tuna hauls as the men of the sea fight the raging waves on the North Pacific!
