(The Sensorite bows and leaves.) (The Sensorites clutch at their heads.) ADMINISTRATOR: And the antidote is to be given to the young man, Ian? ADMINISTRATOR: And then to our people who are also ill?

A: the Doctor; Q: Who seeks to cure the illness? A: deliberate poisoning; Q: What caused the illness of the Sensorites and Ian? A: The political manoeuvring; Q: What poses a threat to the TARDIS crew? A: the Sensorite City Administrator; Q: Who poses a threat to the TARDIS crew? Summary: The Doctor, Ian, Barbara and Susan arrive in the TARDIS on board aspaceship. 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.
