Billy Casper is 15 years old. Bullied at school and unhappy at home, he doesn't fit in. But when Billy comes across a wild kestrel and realises he can train her, he discovers a new life above the small Northern mining town in which he lives. Together they learn to fly and Billy finds friendship and hope - until one snap decision and an unplaced bet change things forever. 'Kes' is the story of Billy's heart. How it came to beat and how it came to break. The Jack Studio Theatre presents the Off West End premiere of this powerful adaptation of Barry Hines's much-loved modern classic, 'A Kestrel for a Knave.'
