When colossal iron sentinels stir beneath the Cornish moors, the Doctor and Jo Grant uncover a buried terror older than humanity itself — and a force that could awaken the end of the world.
A storm has battered the coastal village of Penharrow, but something far older than the sea is beginning to wake beneath it.
After a series of mysterious tremors and the discovery of strange footprints too large to be manmade, the Doctor and Jo Grant are drawn into a desperate race against time. Ancient guardians — vast iron constructs built by a civilisation long forgotten — stand silent over the cliffs, their purpose lost to myth. But the Doctor knows better. The Iron Giants were not built to protect mankind. They were built to contain something far worse.
As the Earth trembles and the ground itself begins to fracture, the Doctor must risk everything — even his own life — to stop the awakening of the Karsheen, creatures of impossible energy that can twist the fabric of worlds.
A story of storms, secrets, and sacrifice.
