From the liner notes

Helen Mirren and Jeremy Irons star in Elizabeth I, a two-part HBO Films miniseries event that explores the intersection of the private and public life of Elizabeth I (Mirren) in the latter half of her reign, offering a personal look at her allies, her enemies and her suitors as she struggles to survive in a male-dominated world. Part 1 explores Elizabeth's tempestuous relationship with the Earl of Leicester (Irons) as it survives a French suitor, war, treason, and illness. Part 2 follows Elizabeth through her later years, during which she had an equally passionate affair with the young, ambitious Earl of Essex (Hugh Dancy), who had been raised, ironically, by his stepfather Leicester. In the end, Elizabeth I sheds light on one of the most popular members of the monarchy who held absolute power over everything... except her heart.
