Alice Wright, hoping to escape her suffocating life in England in the 1930s, makes the bold decision to marry handsome American Bennett Van Cleve and follow him to a small town in Kentucky, which, however, soon defy her expectations. So when the women of the area are invited to join the Riding Library, an initiative of Eleanor Roosevelt, the First Lady of the USA, to distribute books to vulnerable and isolated citizens, Alice takes part with enthusiasm.

There she will find a community of special women, while the head of the library, the poised and emancipated Margery, will soon become her most important ally. Even though, in order to fulfill their mission, the Mounted Librarians face all kinds of challenges, in a landscape that takes your breath away with its beauty but does not forgive carelessness, they are dedicated to their work: to provide books to those who have not never access them and change lives.

Their adventures – and the adventures of their beloved men – make up an unforgettable drama based on true events.
