One winter's day in 1673 young John Ridd is riding home from school, across the wild lonely hills of Exmoor. He has to pass Doone valley - a dangerous place, as the Doones are famous robbers and murderers. All Exmoor lives in fear of the Doones.

At home there is sad news waiting for young John, and he learns that he has good reason to hate the Doones. But in the years to come he meets Lorna Doone, with her lovely smile and big dark eyes. And soon he is deeply, hopelessly, in love . . .
