The Doctor discovers that the T-Mat Base on the Moon has been taken over by a group of Ice Warriors, led by the villainous Slaar. Their home is a desolate and dying planet, the Martian invaders see Earth as a world ripe for conquest. 

But before they can colonise Earth they must dramatically alter its atmosphere. And so they unleash the Seeds of Death ... 
 

Deadly Ice Warriors, exploding seed pods and a lethal fungus are among the terrors in store in this feature-length space adventure.

It is the 21st Century and Earth is totally dependent on T-Mat, a revolutionary form of instant travel. When the system breaks down, the Doctor and his friends make a hazardous journey to the relay station on the moon only to find that it has fallen into the hands of the Ice Warriors who plan to invade Earth. Using T-Mat the Ice Warriors transport seed pods to Earth which burst, disgorging a deadly Matian fungus. This spreads rapidly extracting vital oxygen from the atmosphere. Can the Doctor outwit the evil Ice Warriors and destroy the fungus in time to save a dying world?
