Doctor Who and the Seeds of Doom — Philip Hinchcliffe

PLANTS ATTACK MAN

In the frozen reaches of the Antarctic, deep in the permafrost, the World Ecology Bureau uncovers two of the strangest pods ever known to man--two pods that have been buried in ice for thirty thousand years.

Then, one of the pods is destroyed, and the second is stolen...

The pod is an alien Krynoid--hostile to all animal life--including man. Only Doctor Who is able to stop its spreading tentacles of destruction. But will he be in time to save mankind?
