In 1950s Scotland, everything is changing for the Grace girls. Heather and Kirsty Grace are sisters growing up in Rowanhill, near Glasgow, surrounded by a big Irish family and a host of friends and neighbours. Older sister Heather has everything that should make her happy - a steady job, good friends and a boyfriend who wants to marry her. Why then does she long to escape her small town and find love and excitement among the bright lights of the city? Kirsty, two years younger, also yearns for a different kind 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 offers to become her manager, Heather wonders whether Larry has his sights set on more than just Kirsty's singing talents. The Grace girls are lucky to have such a caring family around them. It's a dangerous world out there and there are plenty of pitfalls and temptations ahead of two young women in search of adventure...
