Martyn Huntley

Arriving in the town of Tombstone, the First Doctor finds himself involved with gunmen out to kill Doc Holliday...

The Doctor, Ian, Barbara and Susan arrive in the TARDIS on board a spaceship. Their initial concern is for the ship's human crew, who are suffering from telepathic interference from the Sensorites, but Susan communicates with the Sensorites and finds the aliens fear an attack by the humans and are just defending themselves. Travelling to the Sense Sphere (the Sensorites' planet) the Doctor seeks to cure an illness to which the Sensorites and Ian have succumbed, but finds it has been caused by deliberate poisoning. The political manoeuvring of the Sensorite City Administrator poses another threat to the TARDIS crew as he seeks to discredit and implicate them.

The TARDIS arrives in a desolate future London, where the Doctor discovers his old enemies the Daleks have taken control of Earth.

Les aventures du Docteur, un extraterrestre, un Seigneur du Temps originaire de la planète Gallifrey, qui voyage à bord d'un TARDIS (Temps À Relativité Dimensionnelle Inter-Spatiale), une machine pouvant voyager dans l'espace et dans le temps. Le TARDIS a l'apparence d'une cabine de police (construction typiquement britannique ressemblant à une cabine téléphonique), le système de camouflage étant resté bloqué. Comme tous les Seigneur du Temps, le Docteur possède treize vies, ce qui explique sa capacité à changer de corps lorsqu'il est proche de la mort.
