A geologist uncovers a ring of oddly-marked stones in a lonely mountainous area. The markings and size of the ring would suggest the landing site of a spaceship. In the centre of this ring is an unknown electronic device. The geologist discovers too late that he has stumbled upon an alien recording device left behind to monitor and relay information about planet Earth.
