Time Team travel to Alfoldean in West Sussex to uncover a Roman mansio or stopping-place, and hence the story of the whole settlement. The dig takes place in ploughed fields on both sides of the A29, or what the Romans knew as Stane Street. But atrocious weather and the sheer scale of the site push the team's resources to the limits. They are joined by Roman Sussex specialist Miles Russell and archaeologist Mike Luke. Phil gets a new hat. They are visited by pupils from the nearby Christ's Hospital School. Farrier Cliff Barnes uses the school forge to make hipposandals - precursors of the modern horseshoe.
