Scrappy Scottish teenager Gemma has never backed down from a fight. That was the way of life in the small-town, low-income housing scheme where she grew up, southeast of Glasgow. But her grandfather, who raised her from infancy, won't accept that.

But is that enough action for Gemma? In a classic coming-of-age fashion, Scheme Birds asks what causes a person to change – and whether it's ever too late to do so.
