The movie traces three key moments: the six-year-old boy, already driven by an extraordinary spiritual sensitivity; the eleven-year-old boy, curious and brilliant; and the fifteen-year-old in his first year of high school, self-aware and determined, capable of approaching everyday life with an extraordinary outlook.
