The Time Lords direct Doctor Who and Jo Grant in their TARDIS to a bleak planet in the year 2471, where they find colonists from Earth under threat from mysterious, savage, monster lizards with frightful claws! And hidden upon the planet is the Doomsday Weapon, for which the Master is intently searching.

Who are the mysterious humans from the distant future now living in that distant past? Somebody's interfering with time. The Doctor, Rose and Captain Jack arrive on modern-day Earth to find the culprit - and discover a Neanderthal Man, twenty-eight thousand years after his race became extinct.
