It's 1954 and, in Barbados, Ruby Haynes spots an advertisement for young women to train as nurses for the new National Health Service in Great Britain. Her sister, Connie, takes some persuading, but soon the sisters are on their way to a new country - and a whole new world of experiences.

As they start their training in Hertfordshire, they discover England isn't quite the promised land; for every door that's opened to them, the sisters find many slammed in their faces. And though the girls find friendships with their fellow nurses, Connie struggles with being so far from home, and keeping secret the daughter she has left behind in search of a better life for the both of them . . .
