The Ark in Space

Written by Robert Holmes

"Homo sapiens. What an inventive, invincible species. It's only a few million years since they crawled up out of the mud and learned to walk, puny, defenceless bipeds. They've survived flood, famine and plague. They've survived cosmic wars and holocausts, and now here they are amongst the stars, waiting to begin a new life, ready to outsit eternity. They're indomitable. Indomitable!"

Many thousands of years in the future, Earth becomes uninhabitable. Aboard space station Nerva, the remaining survivors of the human race drift among the stars in suspended animation. The Doctor, Sarah and Harry arrive to find vital systems have been sabotaged. As mankind begins to awake from its enforced deep sleep, the Doctor discovers that they are not alone... The Wirrn are an insect race that inhabit the cold depths of space. But they too have found the Ark and its sleeping occupants. Can the Doctor prevent the last of the human race from becoming the Wirrn's new source of food...?
