In 1838, at the age of 18, young princess Alexandrina's life is transformed when she ascends the throne of Great Britain and becomes Queen Victoria. Suddenly finding herself freed of the repressive shackles placed on her by her mother's advisor, Conroy, she builds a new alliance with the charismatic prime minister Lord Melbourne.

Lord Melbourne's resignation as Prime Minister leaves Victoria devastated. As Lord Melbourne's popularity in the house wanes, the Tories eagerly await their imminent triumph, while the Duke of Cumberland views it as a chance to prey on his niece's vulnerability.

A Chartist uprising in Newport underlines the instability of the monarchy. King Leopold suggests to Victoria that she consider Prince Albert as a possible consort, a development that results in the young queen being surrounded by suitors.
