School leaver Maisie Miles suspects her father, a small-time crook, has an ulterior motive for insisting she gets a job at the W. D. H. O. Wills tobacco factory but keeps it to herself.
She's befriended by effervescent Phyllis Mason and kind-hearted Bridget Milligan who take pity on her and take Maisie under their wing.
But beneath their happy go lucky exteriors they all harbour dreams and worries about what the future holds.
Engaged to be married Phyllis dreams of romance and passion but when it comes there are dire consequences.
Bridget seemingly the level headed one harbours a horror of something unspeakable that she cannot easily come to terms with.
There's great comradeship at the tobacco factory, and with the advent of war everything is about to change and even the closest friendships are likely to be strained.
