When Valerie and Euan's car breaks down in remote countryside near the Antonine Wall they have a problem. With their mobiles left at home and an evening out arranged in Glasgow, they have to find help fast.

This comes in the form of Petey and Ida and their twenty-year-old daughter Christine, a farming family who live and breathe the history and traditions of the small area of earth they've made their home. Dark Earth premiered at the Traverse Theatre, Edinburgh, in July 2003.
