Host Jessica Greenwell and superfan Adam Ferry discuss how Doctor Who has changed since its very first episode, in 1963.

The Doctor is summoned to the Gallifrey only to find his home planet in the grips of a dangerous crisis following the assassination of the Time Lord President.

In his defence, the Doctor presents evidence through a screen linked to the Matrix, showing the details of his actions on the spaceliner Hyperion III in his own personal future.

The TARDIS materialises on Earth in the year 1911 inside an old priory owned by Egyptologist Marcus Scarman. Scarman has been possessed by Sutekh, last survivor of the god-like Osirans, who is held prisoner inside a pyramid in Egypt by a signal transmitted from one on Mars. Sutekh desires his freedom and instructs Scarman to construct servicer robots - which look like Egyptian mummies - to build a missile with which to destroy the Martian pyramid. The Doctor foils this plan by blowing up the missile.

The Doctor uncovers the starliner's secret.

The Doctor gives evolution a nudge to vanquish his enemies.
