Hugh returns home to the West Country where he teams up with the region's most progressive fishermen to investigate commercial developments in sustainable fishing.

Hugh visits the Hebrides in Scotland where he learns about how the sea and the food it provides have shaped life on the islands. He also sources shellfish and sustainable salmon, and takes over Skye's chippy with only eco-friendly fish he has caught himself.

Hugh heads to the Channel Islands to cast his fishing rod into the ocean. What he catches, he cooks, either on board his boat or on the beach.
