The Hairy Bikers continue their journey around Britain, meeting passionate, skilled heritage volunteers and taking part in the most exciting restoration projects of our industrial past. It is full steam ahead in Wiltshire as they help rebuild an early traction engine before seeing how they revolutionised farming, in Derbyshire they tackle a hundred-year-old cotton spinning mule that has laid dormant for decades and attempt to weave their own Hairy Biker cloth and in Cheshire they restore a rare barge once used to transport coal on Britain's canals.
