Two RAF fighter jets are on a training flight over Northeast Scotland when one of them is plucked from the air and promptly disappears. UNIT are called in, and the Doctor and Brigadier Lethbridge-Stewart are soon on the scene. They enlist the help of a local military officer - a young lieutenant by the name of Mike Yates. The Doctor discovers a link to the recumbent stone circles that are plentiful in this part of Scotland. The stones are thousands of years old and are soon revealed to hold a terrible secret.

Nineteen thirty-five: a message from a Time Lord in trouble sends the Eighth Doctor and Charlotte 'Charley' Pollard to the streets of London's West End, in search of a mysterious alien adversary - unaware that something monstrous is already on their trail. They soon discover that an insidious conspiracy is indeed at work, its tentacles extending the length of the British Isles.

The Doctor and Leela find themselves in the middle of London at the time of a new energy crisis.
