In 1950s Scotland, life is changing for the Grace girls.

Heather and Kirsty Grace are sisters growing up in Rowanhill Village, near Glasgow, surrounded by a big Irish family and a host of friends and neighbours. Older sister Heather seems to have everything – a steady job, good friends and a boyfriend eager to marry her. Why then does she long to escape small town life and find love and excitement among the bright city lights?

Kirsty, two years younger, also yearns for more out of life. Although she works in a local chemist, at nights she sings with a band in church halls and clubs. When a charismatic Irishman, Larry Delaney, spots her singing one evening and soon becomes her manager, Heather suspects Larry has his sights set on more than just Kirsty’s singing talents. Young cousin Lily brings laughter and life into the Grace family, but when fate singles her out, she is forced to find a strength and determination beyond her years.

Although the Grace girls have a warm, caring family around them, 1956 brings a dark winter of fear and suspicion to all women in the Glasgow Area. Just as Heather and Kirsty begin to enjoy the wider world outside Rowanhill, they suddenly find their wings are in danger of being clipped.
