Gioia, 18 years old, lives with her widowed father on their farm in the middle mountains. When she is not looking after the sheep, she is helping the villagers by delivering the farm's products, distributing water from the so-called "miraculous" fountain and helping the elderly. Everything would be fine if her father, Bruno, who loves her very much, did not play games of chance. Burdened with debts, he must gradually strip himself of his possessions. Gioia tries to help him, but the addiction is too strong. With time she manages to convince him to join a rehabilitation center for inveterate gamblers. But to do so, he has to go to the big city. Gioa goes with him, settles down in a hotel, takes a job as a pizza delivery girl and supports Bruno in his difficult fight.
