Greg and Price are having little success on the tractor. Greg remembers the tractor which was in the quarry (in Episode 2), and also the stockpile of food that had been collected there. The quarry is within a day's return trip, so they send Price & Barney off in the van to see if there's anything left there.By nightfall, they haven't
returned. Greg's opinion of Price falls even lower, as he assumes that he's taken advantage of the liquor stored up at the quarry.
That night, another couple of survivors arrive at the house. A woman driving a land-rover, towing a caravan, inside which is her boss - they were boss & secretary before the death, and have maintained that relationship afterwards. The man is Arthur Russell, a successful businessman, his secretary is called Charmain.
They're heading northwards to live on an island Russell owns off the coast of Scotland.
Greg and Abby don't hide their dislike of Russell, and Greg commandeers the Land Rover so that he and Paul can go after Price.
They find Price and Barney pinned down by gunfire from a hut at the end of the quarry. They've been unable to move without being shot at. Greg and Paul climb to the top of the quarry to survey the scene. There are several guns pointing out of
the hut down the quarry, but it is undefended at the rear. Greg doubles round and climbs down the quarry side behind the hut.
He peers inside and sees there is only one man in the hut, and he has several guns rigged together, fired by pulling strings. Greg bursts in and overpowers the man, who he recognises as Vic Thatcher, the man Anne Tranter had left to die in Episode 2.
Vic has survived thanks to the food supplies in the hut, but his legs are
useless. He rigged up the guns to protect his stockpile. Greg convinces him that he hadn't realised what Anne had done, and offers him a place in the community. Vic is tempted to stay where he is, as he's convinced that Anne will one day return to claim her stockpile of goods, and he wants revenge. However, as he's seen no other people since being abandoned, he decides to go back with them.
