It's summer and the Peachey family is in crisis - again. Youngest child Betty Peachey is trying to persuade the family to go to the Faraway Campsite of Ma Peachey's idyllic dreams. But most of the Peacheys are still resisting. Pa Peachey is convinced that terrible dangers lurk in the `wild', Ollie only cares about whether there's a `disco', and Ava has her nose deep in philosophy books...But marvellous McTavish, always one step ahead of the Peacheys, quietly works out a way to get the family enjoying their holiday, together.
