The trawler, Isabella Greig, moored at Granton. She sets off. On the outward journey the drew check and prepare the nets. On arrival at the fishing grounds the trawl is lowered.

A storm blows up and the trawler has to ride out the rough seas. The seagulls circle the ship.

When calm returns the nets are hauled in by the crew and the catch is hoisted aboard, as the seagulls flock round. The fish are tipped out on the deck. The crew gut the fish and throw them into baskets.
