Overview: The newest boat in the Peterhead fishing fleet Westro, skippered by James West, heads to fishing grounds in the North Sea hunting for prawns. Westro cost James two million pounds so he has to work hard to pay off his debt. On board with James is his 19-year-old brother and first mate, Stephen, who must help James work out how to fix a tricky problem when a rope gets tangled around the boat’s propeller. Another trawler, Zenith, is also in search of prawns, skippered by Adam Robertson. They take a gamble to fish just fifteen miles off shore in a location Adam hopes will bring in a good catch. Adding pressure to Adam’s trip is an unusual passenger, Aisling Duncan, a scientist from the Scottish Fishermen’s Federation. Aisling must work around the clock alongside seasoned fishermen to count and measure the catch for vital research into fish stocks in Scottish waters. Back on shore, ex-fisherman Stephen Bruce has started a new career, as a mobile fishmonger. Everyday self-starter Stephen competes against the biggest buyers in town for the finest catch at Peterhead Fish Market. He then takes his seafood from village to village across Aberdeenshire selling to the public, but will he get any customers?
