Starring Tom Baker as the fourth Doctor! Two alien seed pods are found buried in the Antarctic permafrost. The Doctor realizes they are from a Krynoid, a form of alien plant life that infects and transforms all animal life. One of the pods infects a scientist at an Antarctic base, but the developing Krynoid is destroyed by a bomb set by two men, Scorby and Keeler, who have made off with the other pod for their boss, eccentric plant collector Harrison Chase. At his mansion in England, Chase arranges for the pod to be opened under controlled conditions, but Keeler is infected instead and becomes a horrific creature, one that the Doctor must defeat at all costs!
