Documentary series about a group of trawler fishermen in Peterhead, Scotland. In a week of appalling weather and even worse catches for the skippers of the pair trawlers Sunrise and Ocean Dawn, John Stevenson and Ian Ritchie find themselves blown clean across the North Sea and forced to take shelter in Bergen, Norway. With the beer costing eight pounds a pint, they cannot afford to stay in port for long and must return to sea to fill their holds with fish, even the low-priced 'black' Coley that they usually spurn. Nothing at sea is easy, however, and their trip from hell is about to get a whole lot worse with a catastrophic engine failure for one of them and a dramatic mercy dash by the other. John Buchan Snr, skipper of Ocean Venture, has been fishing so long that he is known as King Cod. Still ready to learn new tricks, he leaves familiar territory to embark on an expedition into the Atlantic in search of exotic species and encounters an astonishing and rare creature from the deep. He also has a close encounter with a Spanish trawler which spirals unexpectedly into an international incident and forces John to reconsider his holiday plans for the year.
