A young boy named Wheeler, played by Andrew-Ray, is a starving orphan living on the streets. One day, he discovers a cameo depicting Queen Victoria, portrayed by Irene Dunne. Although he doesn't recognize her, someone explains that she is the "mother of all England", a phrase that sparks Wheeler's curiosity. Interpreting this literally, he decides to visit Windsor Castle to see her for himself.
Despite his rough circumstances, Wheeler manages to sneak into the castle. His appearance catches the attention of a kindhearted maid named Kate Noonan, who initially considers helping him escape. However, before she can safely send him away, Wheeler must hide when the Queen herself enters the dining hall. During a meal, Wheeler dozes off, and his loud snoring leads to his discovery. The boy is then caught and forcibly bathed, which heightens his fear and confusion.
He is questioned by John Brown, played by Finlay Currie, a close confidant of Queen Victoria. Brown quickly realizes that Wheeler is not part of any conspiracy against the Queen, and instead of punishing him, he personally takes the boy on a tour of Windsor Castle, despite the protest of the castle's authorities. In a lighthearted moment, Brown drunkenly encourages Wheeler to sit on the throne, emphasizing the boy's innocent wonder at the grandeur around him. However, their tour is cut short when officials intervene, leading to Wheeler being taken into custody for interrogation.
Wheeler's plight becomes widely known among the public, sparking rumors and media attention. Meanwhile, Prime Minister Benjamin Disraeli, played by Alec Guinness, has been unsuccessful in persuading the widowed Queen Victoria, portrayed by Irene Dunne, to end her self-imposed exile. Since her husband's death fifteen years prior, she has retreated from public life, and Disraeli sees Wheeler's story as an opportunity to influence her.
Disraeli delivers a speech in Parliament, subtly criticizing the Queen's seclusion by highlighting Wheeler's innocence and the importance of her engaging more with her subjects. Queen Victoria is furious when she learns of Disraeli’s actions, feeling that her autonomy is being undermined. She firmly refuses to become more accessible to her people, despite pleas from John Brown and others.
However, during this period, Wheeler’s story touches the Queen emotionally. When Wheeler is brought to her for a meeting, she is genuinely moved by his innocence and resilience. This encounter sparks a change in her perspective, and she begins to reconsider her withdrawal from public life. Ultimately, Wheeler's plight helps to inspire her to step out of seclusion and re-engage with her role as monarch.
In a romantic subplot, Lady Emily Prior, played by Beatrice Campbell, and Lieutenant Charles McHatten, a Guards officer played by Anthony Steel, face obstacles in their love. The Queen disapproves of their relationship due to McHatten's lower social standing, and they attempt to elope twice. Each time, McHatten is called away on urgent business related to Wheeler’s case, thwarting their plans. After a third attempt, and following Queen Victoria's eventual acceptance of their love, the couple is finally able to marry.
Throughout the film, themes of compassion, duty, and personal sacrifice are explored as the characters navigate societal expectations and personal feelings. The story beautifully depicts how a young boy's innocence can influence a monarch's decision to re-engage with her people, ultimately reinforcing the importance of empathy and understanding in leadership.
