This episode is a special programme from the Firth of Forth. Dougie is out sea swimming with the man who takes a daily dip before work, while Arlene is on the Isle of May, where seabirds are under the threat of food shortages. Meanwhile, Euan is up-river to see the industrial land reclaimed by nature, and Nick takes the Landward food van to North Berwick to cook up some locally caught lobster.
