During World War II, the tiny Scottish island of Today runs out of whisky. When the freighter S.S. Cabinet Minister runs aground nearby during a heavy fog, the islanders are delighted to learn that it's cargo consists of 50,000 cases of whisky. When officious English commanding officer Captain Waggett (Basil Radford) demands return of the liquor, shopkeeper Joseph Macroon (Wylie Watson) and his daughters Peggy (Joan Greenwood) and Catriona (Gabrielle Blunt) spearhead an island rebellion. Also known as TIGHT LITTLE ISLAND.
