Set in 16th century England, Mary Stuart follows the tale of Elizabeth I who is threatened by the survival of her Catholic cousin, Mary, who has been a prisoner for 19 years. Wrestling with her own conscience - and Mary's popularity - the Queen agonizes over the fate of her cousin amid fears for her own survival. Alex Kingston (E.R.) stars as the doomed Mary, Queen of Scots, in a 14-member ensemble that includes Sheelagh Cullen, Kenneth Danziger, Martin Jarvis, Christopher Neame, Alan Shearman, W. Morgan Sheppard and Simon Templeman.
