Robson Green begins by travelling around the south-west of England as he goes on a mission to find the conger eel.

The actor explores the Pembrokeshire coast, where he goes in search of sea bass, a special and highly sought-after species. In Saundersfoot Harbour, Robson meets sustainable fisherman Berwyn, who is lucky enough to own one of the very rare sea bass fishing licences. Back on dry land, it's time to see how the bass goes from port to plate in a matter of hours as Berwyn hand-delivers his catch to chef Dougie.
