Episode 4

While the fishing boat Reliance spends the day in port, two of its Ghanaian crewmen take a trip into Peterhead to buy gifts for their families back home. In the evening, the boat heads to the Shetland Isles in search of whitefish and prawns. The boat's nets come up full of mud and sea urchins, which can damage the catch, so skipper John Clarke decides to move to another ground. John's move pays off and he steams home full of prime langoustine and cod. John has been reflecting on the future of his son David, who is hoping to take over as skipper one day. So will John let David take the boat out on his own, and if so, does David think he's ready?

On the Amity, skipper Phil Reid tries a new fishing ground to see if he can find a decent catch. But the hauls are disappointing and even a change in the weather conditions doesn't bring a change in fortune. Phil and the crew keep toiling away but return to Peterhead with 200 boxes of fish and just five prawns. On land, Phil has a tense wait at fishing's equivalent of the Oscars to find out if he's won an award for a new kind of net he has developed.
