After a lifetime of travels that have taken her across the globe, Joanna Lumley is making her most personal journey yet. Starting at Tilbury Docks in Essex she heads north, making a nostalgic return to Coronation Street, before ending the journey in Whitby.

This week Joanna travels through Scotland and Northern Ireland. Starting in the Outer Hebrides, she explores the Harris Tweed industry and drives a herd of Highland Cattle across the sands at low tide to their winter grazing. Next Joanna heads to Eilean Donan Castle, the location for her very first episode of the New Avengers, where she strikes some Purdy moves as she scales the battlements.

Episode three takes Joanna from North Wales to the West Country, ending in her home town of London. After stopping in the slate quarries of Blaenau Ffestiniog, Joanna heads to Carmarthen to meet GoCompare singer Wynne Evans. In Cornwall she visits the legendary St Michael's Mount, before heading to Southampton to meet a family of Travelling Showpeople who have been in the fairground business for generations. She also meets a couple who have ‘re-wilded' their 3500-acre country estate. Ending her journey in London, Joanna tracks down Allan Willmott, 95 part of the Windrush Generation whose face she spotted at Tilbury at the beginning of her journey and reflects on what she has seen in her travels.
