The first episode heads to the world-famous Brixham fish auction, which has been going for over a hundred years but is now experiencing the biggest boom in its history, turning over up to a million pounds a week. For sellers like trawler captain Alan Scales there is much at stake. He needs to get good prices for his fish or he can't pay his crew. Buyers range from big traders like Sean Perkes, spending tens of thousands of pounds a day on fish that will be exported round the world, to local fishmongers like Tracey Beer, battling to keep her shop afloat in challenging times. The programme explores how the Brixham trawler transformed the industry in the 1800s, allowing fisherman to go further and fish deeper than ever before.
