A 1930s British summer Bank Holiday starts at midday on Saturday with a rush for the trains to the sea-side. Doreen Richards under the name Miss Fulham is off with friend Milly to a beauty contest. Geoffrey and nurse Catherine Lawrence have decided to spend an illicit week-end in the Grand Hotel, although Catherine's mind keeps turning back to the hospital case she was working on. Arthur, May and the children are set on a more straight-forward excursion of sea, sand, and pub. Meanwhile, the manager and performers of the "Follies" on the pier pray for rain.
