 Harriet Green (Jessie Matthews), a beloved and radiant music hall star of the Edwardian era, has a guilty secret: She has a baby daughter, born out of wedlock. Harriet leaves her public and flees to South Africa to raise her daughter quietly. The years pass, and now her daughter, Harriet Hawkes (Matthews again), returns to London as a young show-biz hopeful. Tommy (Barry MacKay), a wily publicity man, knowing that young Harriet is a dead ringer for her famous mother, convinces a theater producer (Sonny Hale) to star her in a new revue as none other than the original Harriet Green, miraculously untouched by old age. The ruse works too well: Now the public believes Harriet is a well-preserved 60-year-old and Tommy is her son. The deception is more than merely inconvenient, because now Harriet and Tommy have secretly fallen in love.
