You don't expect five-star amenities on a caravan site - but hot water is on most people's list of basic essentials. At the site where Bert and Betty Jones live, however, the lists were discarded long ago, and now it's action stations to be first in the shower before the water turns from lukewarm to ice-cold. It's this fact, allied to a never-ending search for la dolce vita, which persuades Bert to take matters into his own hands. Betty will, he decides, have her own personal shower room.
