Documentary series about a group of trawler fishermen in Peterhead, Scotland. On the North Sea comradeship counts for everything. The pair trawlers, Ocean Dawn and Sunrise, always work together and their skippers Ian Ritchie and John Stevenson look out for one another through thick and thin. This fishing trip will be their toughest yet as ferocious weather, poor fishing and problems with a new net bring unexpected pressures to this successful working relationship. Can they win through? On the Arcane, father and son team Charles and Charlie McBride have an unusual problem - they're catching too much of the wrong kind of fish. They've already been hit with heavy penalties due to over-fishing, and the quota restrictions on cod mean that's the last fish they want in their nets. Deep in debt they find themselves racing against the clock to throw back thousands of pounds worth of this valuable fish before they die. On the newly launched Viking Monarch, the skipper Jason Scolfield has deeper pockets. She's the largest white fish trawler in the UK. Jason's just spent half a million pounds on her refit and filled her tanks with 50,000 pounds worth of fuel. But Viking Monarch's new paint job hides a secret- she was previously known as the Solstice, an Irish trawler with a history of bad luck and tragedy. Will a new name and a lucky horseshoe be enough to change her fortunes?
