Alison Steadman visits the Inner Hebrides

In this episode Alison visits the tranquil Isles of Scilly, which have some of the most spectacular unspoilt beaches in Europe. On the lesser-known 'Off Islands' of Tresco, Bryher, St Martins and St Agnes, she discovers one of the finest sub-tropical gardens in the northern hemisphere, visits a Robinson Crusoe-style desert island with white sandy beaches and a history made famous by Harold Wilson, and gets hands on at one of the world's smallest working dairy farms. She also discovers how the welcoming islanders have had to find inventive ways to keep hold of their slice of island paradise.
