When all hope is gone, are dreams enough? After losing both her parents, 16-year-old Merrion Roberts is left to bring up her baby sister. Unable to cope alone, she teams up with Rhonda Rees, a trained milliner, who also has a young baby. They share rooms in notorious Tiger Bay in Cardiff, struggling to make ends meet. In time, though, they are able to open up a little shop and it seems as if life is looking up for both young women. But fate soon intervenes, and they are reduced to living in even greater squalor, barely able to eke out enough money to support themselves let alone their two children. Meanwhile, Merrion's brother and her childhood sweetheart have both gone to sea and she has almost given up hope of ever seeing them alive again.
