The fish sold at market in Peterhead comes from fishing boats all over Scotland, even as far as northern harbour Scrabster, where fishing boat Reliance is preparing to set sail. On this trip, owner of Reliance, John Clark, is stepping aside as skipper to let his 22-year-old son David take the helm for the very first time. John is on board working as first mate and keeping a close eye on David, making sure he is doing everything by the book, but will David have what it takes to prove to John he can skipper Reliance alone?

On the north east coast, trawler Sardonyx is also heading out to sea, skippered by Michael Watt with his brother Brian at his side as first mate. They are on the hunt for squid in the Moray Firth, less than a mile from shore. Fishing close to shore still comes with dangers for the Sardonyx and its crew, and they soon have a problem with the net. They can’t lift their 600 kg gear out of the water, but luckily Michael comes up with a plan to use the crane to help get the catch on board.

On shore, the Robertson family are checking their boat Zenith into the drydock for some vital maintenance work. They are also checking in the Zephyr, a trawler they purchased just ten months ago, which needs an overhaul to match it to their flagship Zenith. There are just seven days to get the boats cleaned, painted and replacement parts in place before the boats must go back into the water. Show less
