Judy Hamilton was born in the Cardiff docklands. Homeless after the death of her grandmother, she finds friendship, work and lodgings with Edyth Slater, above her bakery in Cardiff's colourful Tiger Bay. While attempting to make her way in a vibrant and complex society, Judy dreams of one day becoming a successful singer and actress.
