In March 1815, Napoleon Bonaparte escaped from exile in Elba. In Brussels, 18 year-old Helen Whitley, knows that war with France between Britain and her allies, is inevitable. A talented artist, Helen is aware of the anxiety and fear underlying the balls, breakfasts, parties, picnics and soirees, held by the British. In an attic, she paints scenes and portraits in which she captures the realities and emotions of daily life during the hundred days before the Battle of Waterloo. While Helen lives with her sister and wealthy brother-in-law, Major Tarrant, she waits for Major, Viscount Langley, to arrive in Brussels and propose marriage. Langley, who serves in the same regiment as Tarrant, is her brother-in-law's closest friend, so Tarrant and her sister have no objection to the match. Helen is grateful to her brother-in-law for including her in his household. Nevertheless, she regrets being dependent on his generosity, so she looks forward to being mistress of Langley's heart and home. Before Langley leaves England to join his regiment, he visits his ancestral home, to inform his parents that he intends to marry Helen. Yet, when he arrives in Brussels to join his regiment, he does not propose marriage to Helen, and her pride does not allow her to reveal the misery caused by Langley's rejection.
