The presenter ventures deep into the Scottish Highlands to meet Iona and her young family on the near-10,000-acre wilderness estate that she grew up on. Whilst in their company, Ben drives cattle on horseback, digs out a dam to ensure the family's hydro-electricity supply and gets to grips with the annual deer cull, and hears how Iona's past prepared her for this extraordinary life in the wilderness.

The presenter meets the Powell family who are living an off-grid existence in a hidden valley in the Black Mountains in Wales. Whilst in their company, Ben climbs into a ravine to maintain the family's hydro electrics, explores the forest with the spirited children, and helps plant the biggest new woodland in Wales for a generation.

Ben journeys to the Suffolk countryside and a secretive patch of woodland, to spend the week with unique character Will, 50, who could be described as a true British caveman. Ben embraces Will's Stone Age-style existence in the forest and discovers how a childhood passion carved Will's future, the price he paid for following his dream, and how he is steering it back around as Ben meets him at a new stage in his prehistoric life.

Ben travels to a unique, tiny island in the Scottish Hebrides where he meets ex-social care worker Philip, who has embraced a new way of life in this small, alternative community. In his company, Ben spends the week cut off from the outside world, in an old lighthouse keeper's cottage, where he experiences the unusual routines of the island's community.
