On the eve of May Day, dark elemental forces begin to disturb the village of Devil's End as the Master summons the demon Azal: unexplained murders, a stone gargoyle come to life, and a nigh-impenetrable infernal energy dome. With the Master fully prepared to destroy the Earth, the Doctor and UNIT - aided by a benevolent practitioner of witchcraft - battle the wicked rites of a secret science wielded by an alien from another world.

Patricia Routledge gives a career-best performance as Queen Victoria in this 1964 series of plays based on the celebrated collection of dramas by playwright Laurence Housman. Self-willed, obstinate, imperious and passionate... a now-familiar description of one of history's longest-serving female monarchs – but Housman's satirical tribute marked a decisive break with the tradition of the uncritical historical portrait. A Broadway hit deemed too disrespectful for public performance in Britain until the late 1930s, Victoria Regina is a frank portrayal of an extraordinarily complex woman, tracing her development from royal teenager to inconsolable widow at the helm of a vast empire, with all her contradictions, prejudices and unconstitutional behavior.

The adventures of The Doctor, a time-traveling humanoid alien known as a Time Lord. He explores the universe in his TARDIS, a sentient time-traveling spaceship. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Along with a succession of companions, The Doctor faces a variety of foes while working to save civilizations, help ordinary people, and right many wrongs.
