Doctor Who: Classic

The TARDIS lands in London where the Doctor, Jamie and Zoe agree to help find Isobel Watkins’ missing uncle.

Brigadier Lethbridge-Stewart confirms that there is something suspicious occurring at International Electromatics. Zoe and Isobel's investigation places them in terrible danger.

The Doctor and Jamie are taken prisoner by Tobias Vaughn who denies abducting Zoe and Isobel. The Doctor suspects that there may be an even greater threat behind Vaughn.

Trapped by Vaughn's men at International Electromatics, the Doctor requests help from the Brigadier and UNIT. A UFO is delivering cocoons to IE – but what is inside them?

The Doctor discovers that the Cybermen are planning to immobilise the Earth’s population by transmitting a hypnotic signal broadcast through International Electromatics products.

Zoe, Jamie and Isobel confront Cybermen in the sewers beneath London. The Doctor hurries to devise a protection from the Cybermen’s hypnotic signal.

The world’s population are unconscious and the Cybermen invade in force. The Doctor desperately attempts to persuade Vaughn to help him resist the invaders.

The Cybermen have launched their deadly megatron bomb which will destroy all life on Earth unless the Doctor can deactivate the homing signal.
