Episode 3

Stephen Mangan, Sue Perkins and Alison Steadman ditch their maps and compasses and attempt to travel the UK and Ireland using nature as their only guide. The sun, the trees and even sheep droppings are their new sat nav: all providing clues to point you in the right direction.

Alison Steadman takes Stephen Mangan and Sue Perkins across north Wales to her home town of Liverpool. They discover that trekking in thick fog puts their new found navigation skills to the ultimate test, and Alison has an emotional reunion at the theatre where she made her name.
