Ben returns to the Suffolk countryside, and a secretive patch of woodland, to reunite with unique character Will Lord (50), a true British caveman.

Last time, Ben embraced Will's ‘Stone Age' existence in the forest, immersing himself to help Will complete his caveman home. They prepared and ate dinner using primitive tools, Ben learned a range of skills from fire-starting to coracle boating on the river, and he spent time with Will and his dad, arguably one of the best flint-knappers in the world.

Now, almost three years later, Ben discovers how Will's new prehistoric dream is developing and how those closest to him are embracing his new-found passion.

Ben explores the Great Blasket Island off the coast of Ireland, staying with Dan and Emily who are island caretakers on Europe's rugged western frontier. Ben discovers how the couple have adapted to their new lives on the island and what they've achieved while living there. Plus, he experiences fixing a water pump, catching sheep, foraging seaweed and swimming with seals.
