Grandad is running a summer pony camp at the stables for the first time, and Grace and Aaron are helping out. The pony club games soon get quite competitive, and siblings Leah and Ryan can’t stop causing trouble for each other – and the stables. But when one of the stables’ pregnant mares starts to give birth and the foal gets stuck, all the pony camp chaos pales into insignificance.

The vet is called – but a furze fire is blocking the road! Grace and Aaron need to ride out and fetch her … but will they get back in time to save the foal?
