FORESTER: The report itself isn't final enough, Farrow would have telephoned it in to his department. (Forester hushes Smithers with a wave of his hand.) HILDA: Stranger operator here.

(The telephone exchange begins to buzz again, Bert is trying to read a paper, but not having much success.) Insecticide. IAN: By that pile of seeds. DOCTOR: Look out. But we must get her back to the ship. They'd might find that man's body! [SCENE_BREAK]

(Smithers and Forester walk from the door of the house to the door of the laboratory, and Smithers unlocks the door.) Who is this?

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.
