Kes (1970)

"They beat him. They deprived him. They ridiculed him. They broke his heart. But they couldn’t break his spirit."

Bullied at school and ignored and abused at home by his indifferent mother and older brother, Billy Casper, a 15-year-old working-class Yorkshire boy, tames and trains his pet kestrel falcon whom he names Kes. Helped and encouraged by his English teacher and his fellow students, Billy finally finds a positive purpose to his unhappy existence.
