At the end of his spiritual journey across Scotland's Sacred Isles Ben Fogle visits six islands across the Shetland Isles. He meets people whose lives are rooted to these islands' history, visits a tiny church with big ideas and catches up with Shetland chef Akshay Borges, a champion of the island's 'sea harvest'.

This week's island pilgrimage sees Ben Fogle make a very special return to the Isle of Taransay, the island which launched his TV career 20 years ago and started a love affair with Scotland's Sacred Islands.

Ben Fogle explores Catholic island life and whether the physical aspect of the landscape makes it easier to make spiritual connections.

In this first episode, Ben travels across the Inner Hebrides visiting Tiree, Coll, the Treshnish Isles and Iona. Following the ancient ‘Hebridean Sea Highways', Ben discovers evocative connections to sixth century Christian Missionaries.
