(Susan moves to operate the scanner control, and they all look up at the scanner. (The Doctor returns to the Console Room from the fault locator.) All of a sudden a gargantuan bee drops out of the sky and lands in a heap by the side of the path. BARBARA: It's alright, it's alright. Both are vital to the growth of things. DOCTOR: We have been reduced roughly to the size of an inch! FORESTER: Does... Smithers know about this? IAN: It would have been rounder than this. IAN: Perhaps that was the only damage to the ship, Doctor. Murdered! So indiscriminate. The doors of TARDIS opened, that means the space pressure forced us to reduce! There are many insects which make a vital contribution to agriculture, and these insects must not die. This has been cut by a manufacturer. We spoke on the telephone...
(Forester is dressed as neatly as Farrow, but his manner is calm, decidedly colder and a lot more businesslike.

On emerging, the travelers find the ship has been reduced in size and they are now only about an inch tall. As tiny people, they stumble across a plot by a ruthless businessman,Forester, and his misguided scientist colleague, Smithers, to launch a new insecticide, DN6 - a product so destructive that it would kill not only those insects harmful to agriculture but also those vital to it. Forester is willing to commit murder to ensure the success of his business, as civil servant Arnold Farrow discovers to his cost. The criminals are brought to justice when the Doctor and his friends - hampered by the fact that Barbara is ill from the insecticide - tamper with the telephone in Smithers' laboratory, fuelling the suspicions of the local exchange operator, Hilda Rowse, who sends her police constable husband Bert to investigate.
