Jonathan Cake, Jemma Redgrave and Hugh Bonneville lead an outstanding cast in this mini-series tracing the turbulent political career and tempestuous private life of Oswald Mosley, leader of the British Union of Fascists during the 1930s.

The Master re-establishes psychic control of his robot slave Kamelion. He wants to hijack the Doctor's TARDIS to reach the planet Sarn, where he seeks the healing power of Numismaton Gas to restore himself. Once on Sarn, Turlough comes face to face with his destiny.
A strange signal from Earth draws the TARDIS to the island of Lanzarote, where Turlough rescues a young American girl, Peri, from drowning.

As Turlough is forced to face his past, the Fifth Doctor must stop his oldest enemy from harnessing the revitalising powers of Numismaton gas...
