Milan, 1989. Filippo Degani, a senior year high school student, is an ordinary boy: middle-class family, the boring school routine, the girls, the iron friendship with the inseparable Claudio, the best friend with whom he shares the dates with the girls and the passion for football. In the background, high school soccer tournaments and the exploits of the legendary Milan soccer team of Arrigo Sacchi, Gullit and Van Basten. The equilibrium of this very Italian glimpse on the end of the Eighties is overwhelmed by the arrival, in Filippo’s school, of Robert Horowitz, immediately renamed ‘the Stranger’ – rich, beautiful but above all mysterious: nothing is known of his past nor of the reasons that prompted the family to move from London to the outskirts of Milan. Between memorable soccer matches and night raids, the friendship with the Stranger will turn Filippo’s life like a glove, a revolution that will force him to measure the difficulty of remaining true to himself.
