Search Worlds Without End

On a lonely stretch of Welsh coastline a fisherman is killed by a hideous creature from beneath the waves. When the Doctor and Rose arrive, they discover a village where the children are plagued by nightmares, and the nights are ruled by monsters. The villagers suspect that ancient industrialist Nathanial Morton is to blame, but the Doctor has suspicions of his own.

Who are the ancient figures that sleep in the old priory? What are the monsters that prowl the woods after sunset? What is the light that glows in the disused lighthouse on Black Island? As the children's nightmares get worse, The Doctor and Rose discover an alien plot to resurrect an ancient evil...

Earth, 2099. Global warming is devastating the climate. The polar ice caps are melting.

In a desperate attempt at preservation, the governments of the world have removed vast sections of the Arctic and Antarctic and set them inside huge domes across the world. The Doctor and Martha arrive in Snowglobe 7 in the Middle East, hoping for peace and relaxation. But they soon discover that it's not only ice and snow that has been preserved beneath the Dome.

While Martha struggles to help with an infection sweeping through the Dome, the Doctor discovers an alien threat that has lain hidden since the last ice age. A threat that is starting to thaw.

"Well, I doubt you'll ever see a bigger insect."

Gabby Nichols is putting her son to bed when she hears her daughter cry out. 'Mummy there's a daddy longlegs in my room!' Then the screaming starts... Kevin Alperton is on his way to school when he is attacked by a mosquito. A big one. Then things get dangerous.

But it isn't the dead man cocooned inside a huge mass of web that worries the Doctor. It isn't the swarming, mutated insects that make him nervous.

With the village cut off from the outside world, and the insects becoming more and more dangerous, the Doctor knows that unless he can decode the strange symbols engraved on an ancient stone circle, and unravel a mystery dating back to the Second World War, no one is safe.
