On the way they run out of petrol. Abby goes off in search of a garage, whilst Greg and Jenny set up camp.
Abby finds a notice detailing a nearby settlement. It has been posted by a girl called Lorraine who is surveying the area with a man called Charles Vaughan.
In of the houses, Charles and Lorraine discover a young boy called Mick who agrees to join their community. As they leave the house, Charles spies a stray pig and attempts to catch it.
Lorraine and Mick cheer him on and eventually he catches it. Shortly after, the trio meet Abby, Jenny and Greg at the garage.
Back at his caravan Charles explains to them that he was an architect before the sickness, who had already been living a self-sufficient lifestyle. He now leads a settlement at a farm, but wants to expand. He has some impressive plans for the future, and is already talking about restoring hydro-electric power.

Abby decides she wants to carry on to her home. Jenny and Greg decide to go with her having found out about Charles activities and beliefs.
Charles tries to persuade them to stay but they leave after helping him to build a funeral pyre for the dead members of his community.

Many principles and themes are introduced here which are to become mainstays of the series: the quest for hydro-electric power, the issue of re-population, the danger of roaming packs of dogs and the pattern of the death plague.
