S1·E414 The Grass Arena

Brutalised at home and school, John Healy drinks a promising boxing career into the "grass arena" - the savage community of vagrant alcoholics. He drifts towards certain death, until a fellow prisoner teaches him chess. His striking new talent leads him to compete in championships where he plays for recognition and a chance to belong. This film won the Michael Powell Award for Best Feature Film at last year's Edinburgh Film Festival and the Grand Prix at the Dinard Film Festival in France.
