An Italian story that began in 1959, in a small mining town, one of many, in the hinterland of Tuscany. The signs of well-being of the economic boom are upon us. People dream of a better life, a home, school for their children, some money to satisfy the simplest ambitions. The mine feeds everyone, but everyone suffer a lot. The miners in the first trade union movements, through strikes, they suffer badly to obtain improvements in wages and safety at work. And there's the sufferance of the families who live in the uncertainty of an increasingly small salary and in the fear of inevitable tragedy that can happen inside the unhealthy guts of the galleries.Marta, a seven-year-old girl, suddenly finds herself thrown from a serene reality, made of runs at breakneck speed in the fields, to that sad and bleak of the immigration in a large and cold northern city, Turin. In fact, the father Nanni, miraculously escaped from a great tragedy, together with his wife Valeria, decides to try his luck by moving to the large industrial center in the north. It will be a long and painful journey, made of sacrifices, humiliations and renunciations. The girl, very close to his father, receives fundamental lessons from him to transform the sudden difficulties of his small life into a long and exciting flight test. There will be wonderful take-offs and dramatic landings, but with courage, determination and obstinacy, Marta will learn to fly, she will learn to detach herself from the ground to reach the highest peaks of her desires.
