Doctor Who: Silver Nemesis

Launched into space 350 years ago, a meteor is returning to Earth – and inside it waits Nemesis, a silver statue made of the living metal validium, the most dangerous substance in the Universe.

Evil powers await the statue's return: the neo-nazis de Flores and his stormtroopers; Lady Peinforte, who saw Nemesis exiled in 1638 and has propelled herself forward in time; and the advance party of a Cyberman invasion force.

And in the garden of a Windsor pub, the Doctor and Ace are enjoying the timeless sounds of a jazz quartet ...

This story celebrates 25 years of Doctor Who on television.
