After hunting for food, Masklin, a 4-inch-high (100 mm) Nome, returns to his burrow, and argues with his tribe elders about the lack of food and that they have no fire for heat. Masklin decides that a lorry might take them to a better place, but as he wonders, a fox attacks one of the elders, Mr Mert. Masklin chases the fox onto the motorway, killing both the fox and Mr Mert. Masklin decides right then they all have to flee.

Masklin and his tribe see the Abbott, leader of the Stationeri, who act as the Store's priesthood. On the way, they are met by Hardware bandits who are soon driven off. They meet with the Abbott, who does not believe them.

Gurder presides over the Abbott's funeral, where it is revealed that he was chosen by the old Abbott to succeede him. Meanwhile, Masklin comes up with a plan to save the Nomes.

The Duke is distressed at the disappearance of his son. Although he still does not believe in an Outside, he agrees to help Masklin, as he feels it might lead him to Angalo.

Prices Slashed sees Gurder denouncing the 'Demon', and is startled into dropping his lighted cigarette into the petrol. With no time to fix the door, the lorry crashes through moments before the petrol ignites and causes an explosion. They stop a short way down the street to see the store on fire. They drive off and, after a number of close calls, a police car begins pursuing them. The first scene of the first episode then repeats, this time showing Masklin and Dorcas cutting the police cars wiring while the Nomes in the truck hide. The lorry comes to a stop in an abandoned quarry near an airport. Masklin tells the others that they must move on at some point and try to get home. As they watch Concorde fly over, Dorcas remarks that it would be easier to drive than a lorry because it only has three wheels.
