Character Arc
Alan Bates is the unlikely hero at the centre of the story, a mild-mannered former sub-postmaster from North Wales whose stubborn sense of fairness becomes an unstoppable force. When the Post Office terminates his contract over shortfalls he knows he never caused, he simply refuses to accept it, beginning a quiet campaign that will consume the next twenty years of his life.
What makes Bates so compelling is his ordinariness. He is not a firebrand or a showman, just a methodical man who keeps records, writes letters, and patiently connects with others who have suffered the same fate. Through him, a scattered group of frightened individuals becomes the Justice For Subpostmasters Alliance, a movement powerful enough to take on a national institution.
Over the course of the series, Bates endures setback after setback, watching friends lose their homes, their reputations, and sometimes their lives. Yet his resolve never wavers, and his refusal to be dismissed ultimately helps drag the scandal into the light. He embodies the idea that decency and persistence can, eventually, defeat even the most entrenched power.
