The TARDIS materialises in London, 1966, and the Doctor and Dodo visit the recently completed GPO tower. Inside they meet Professor Brett, creator of the revolutionary Will Operating Thought ANalogue computer - WOTAN.
WOTAN is a computer that can think for itself. A project to link up WOTAN to other major computers around the world is being overseen by Sir Charles Summer. WOTAN considers itself superior to humans, and believes it should be the rightful ruler.
WOTAN exerts a hypnotic influence over chosen people, and starts up the creation of mobile computers - the War Machines. Using these machines WOTAN plans to take over the world.
The Doctor manages to capture and reprogram one of the war machines, which then destroys WOTAN. Dodo, back in her own time, opts to stay behind. As the Doctor enters the TARDIS so does Brett's secretary Polly, and her seaman friend Ben Jackson.

Bloopers and mistakes

Notes and trivia
The first draft scripts of this story were by Pat Dunlop.
The story title, writer credit and episode number come up as computer-style graphics, the first use of unusual titling.
The end credits to episode one scroll over a WOTAN symbol.
Gerald Taylor is only credited as the voice of WOTAN for episode four; the other episodes use the caption "and WOTAN", presumably to infer that it is a real computer.
The credit "Based on an idea by Kit Pedlar" is used in the closing credits, instead of the opening titles as later.
Jackie Lane departs during episode two.
