In 16th century England, Sir Thomas More is a devout Catholic who faces a moral and legal dilemma when King Henry VIII seeks his approval for a divorce from Catherine of Aragon to marry Anne Boleyn. As Lord Chancellor, More is pressured by the king and courtiers, including Thomas Cromwell, to support the divorce and the establishment of the Church of England with the monarch as its head. Despite the mounting pressure and knowing the potential consequences, More's conscience and religious convictions prevent him from endorsing the king's wishes. His steadfastness sets him against powerful forces in the royal court, testing his principles and resolve.

More's refusal to accede to Henry VIII's demands leads to his resignation and increasing isolation. He withdraws from public life, hoping to avoid conflict and live quietly with his family. However, his silence is not enough to satisfy the king, who sees it as an implicit challenge to his authority. The stakes escalate as Cromwell and other court officials attempt to implicate More in treason through any means necessary. Amidst political maneuvering and betrayal, More remains firm in his beliefs, even as it becomes clear that his stand for personal integrity and faith may come at a devastating cost.
