Directed by Michael Anderson, it stars Julia Ormond as Catherine and Vanessa Redgrave as Empress Elizabeth.
One of the troubled Catherine's few confidants is an aging, worldly-wise British diplomat, Sir Charles Williams.
On his advice, she gives up her virginity to a soldier who is devoted to her, and bears a child, Paul, who is officially Peter's son and heir.
As the life of the old empress draws to an end, Peter increasingly threatens to take "revenge" on Catherine, and on Russia itself, once he occupies the throne.
Catherine and her supporters at court realize that action is needed to protect her, and some warn that ultimately, the struggle may come down to her life or Peter's.
