On the eve of World War II, a British officer revisits Waterloo Bridge and recalls the young man he was at the beginning of World War I and the young ballerina he met just before he left for the front. Myra stayed with him past curfew and is thrown out of the corps de ballet. She survives on the streets of London, falling even lower after she hears her true love has been killed in action. But he wasn't killed. Those terrible years were nothing more than a bad dream is Myra's hope after Roy finds her and takes her to his family's country estate.
In World War I London, Myra is an American out of work chorus girl making ends meet by picking up men on Waterloo Bridge. During a Zeppelin air raid she meets Roy, a naive young American who enlisted in the Canadian army. They fall for each other, and he tricks Myra into visiting his family who live in a country estate outside London, where his step-father is a retired British Major. However Myra is reluctant to continue the relationship with Roy, because she has not told him about her past.
Hollywood actor Sean Bean tells the story of Waterloo, one of history’s most decisive battles. Sean’s journey of discovery is inspired by his own experiences of playing Napoleonic soldier Richard Sharpe in TV films based on Bernard Cornwell’s best-selling novels. In the programmes he draws on the eye-witness accounts of soldiers who fought at Waterloo to tell the story of the dramatic events of 18 June 1815 as they were experienced by the ordinary soldiers who fought it. He pieces together the chronology of the battle and visits some of the legendary places where the outcome was decided, including the buildings at Hougoumont which witnessed some of the heaviest fighting. He also meets descendants of some of the soldiers who fought at Waterloo, to discover how they remember the achievements of their ancestors.
