Doctor Who - Pyramids of Mars

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 held prisoner inside a pyramid in Egypt by a signal trasnmitted from one on Mars. Sutekh desires his freedom and instructs Scarman to construct servicer robots - which look like Eygptian mummies - to build a missile with which to destroy the Martian pyramid
