Fiona Price takes up the challenge of the 40 km media invitation ride at the Golden Horseshoe on Exmoor '10, the toughest endurance terrain in the UK. She meets Princess Sahhara (an advanced arab mare) with owner Angela and her chaperon, elite squad member Annie Joppe who tells Fiona what to expect. The next day, Fiona and Annie hack to the start to prepare for the vetting. Their aim is to achieve the elusive 'gold award' requiring a minimum speed of 12 km an hour, and completing with a sound, fit horse. The talented arab proves a challenging ride and at half way, Fiona and Annie have got lost leaving the outcome uncertain.
