The fates of the Family, the Lab and the rest of the world come crashing together in a deadly showdown. The Family are in pursuit of Abby's son, Peter, who is in grave danger. The chase leads them to an airfield where the final confrontation takes place.

Tom and Greg are enslaved alongside dozens of others in Mr. Smithson's coal mine. Elsewhere, the Family are desperately tracking Billy, their only lead, across the country. Back at the mine, Greg formulates an escape plan. However the Family are converging on Smithson's as well with their own rescue plans, leading to a dangerous game of cat and mouse.

Fifty-year-old cockney wide-boy Billy is a trader and opportunist, traversing the desolate roads of Britain in his well-stocked container lorry. Billy meets the Family on the road and hands over vital supplies. Surprised, but grateful for Billy's generosity, the Family decides to stay overnight in a cottage close by to help Abby recover from her terrifying ordeal at the Lab.
