Jo Hamilton is a warm, well-liked village sub-postmistress whose life is upended when the Horizon system shows a shortfall she cannot explain. Trusting and conscientious, she even tops up the missing money from her own pocket at first, never imagining that the figures on her screen are wrong rather than her own work.
Her story is among the most heartbreaking in the series, as a community pillar is recast as a thief and forced to plead to a lesser charge to avoid prison. Monica Dolan plays her with quiet devastation, capturing the shame, confusion, and isolation of someone wrongly branded a criminal in the place she calls home.
As the wider campaign gathers strength, Jo finds courage in solidarity, becoming one of the most recognisable faces of the fight for justice. Her arc moves from private humiliation to public vindication, and her resilience makes her an emotional anchor for viewers and fellow victims alike.
