In the final episode of the epic six-part serial The Seeds of Doom, the Doctor and Sarah Jane Smith race against time to prevent the Krynoid, an alien plant species with the power to control all of Earth's vegetation, from taking over the planet and transforming it into a new Eden according to its own twisted vision.

With the help of eccentric millionaire Harrison Chase, the Krynoid has already laid waste to an Antarctic base and a British botanical institute, and is now preparing to unleash thousands of spores all over the world. But the Doctor knows that the true threat is not just the physical power of the Krynoid, but the ideology behind it – the ruthless and amoral belief that life is nothing but a struggle for dominance.

As the Doctor and Sarah race to stop the Krynoid's final plan, they must also confront the dark side of humanity itself, embodied by Chase and his henchmen.
