Old wounds are reopened when Lynley investigates the disturbing death of his godson more than a decade after the boy's disappearance.

The government goes ahead with their plan to give the 456 the children, and the 456 reveal their reasons for wanting them, while Jack and Gwen are shown what happens when they intervene.
Jack explains to the rest of the Torchwood team what happened in 1965, and why the children had to be handed over. Meanwhile, the 456 announce that if their demands aren't met, they will wipe out the human race.
