Perfect Pitch

Ron, a prematurely retired headteacher, and his wife, Yvonne, a would-be marathoner, are on their first caravan holiday. Pitched on a cliff in Yorkshire, the slightly dull, slightly snobby couple grapple with this strange holiday. That evening an elderly caravan appears 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's and Yvonne's lives will never be the same.
