In H P Lovecraft's classic horror story, an old man consents to a radio interview. In that interview a number of terrible truths come out. The truth about an expedition to Antarctica in the 1920's where everyone died horribly.
The truth about an attempt to find the expedition's mysterious killers. The truth about a desolate plateau in the heart of a frozen continent. The truth about life and intelligence on the planet Earth. And the truth about the prehistoric horror that still waits lurking... At the Mountains of Madness.
