Ron, a prematurely retired headteacher, and his wife, Ynonne, a would-be marathon runner, are on their first caravan holiday. Pitched on a cliff just outside of Scarborough, the slightly dull, slightly snobby couple grapple with this strange holiday. That evening, a much older, less attractive caravan appears on the pitch next to theirs and sounds of noisy love-making cause Ron and Yvonne to blush. Steph and Grant, a younger, more working-class pair of seasoned caravanners have arrived and Ron and Yvonne’s lives will never be the same again.
