On a dark night in 1965, a busload of Scottish children is driving down a deserted road. The bus comes to a stop and the children nervously get out. A bright light appears in the sky and the children go towards it. As they get closer one child runs away unnoticed. The light gets brighter and suddenly the night is dark again and the other children have vanished.
Switch to a bright sunny day in 2009. Children are playing in the park or at school recess. Then they suddenly stop everything and are frozen in place. Frantic parents and teachers desperately try to find out what’s wrong but the children are mute and immobile. After a few moments they say in a flat voice “We are coming” over and over. Then it stops as suddenly as it started and the children resume what they were doing completely unaware of what has happened. It all happens at the exact time to every child in the world.
Now of course as anyone who’s been watching the Torchwood series knows, that the obvious thing for the British government to do at this point is to call the Torchwood team and ask them to sort it all out. But not this time since it turns out that the government has a secret that they want kept very badly. So the Prime Minister (Nicholas Farrell) wants all evidence of the secret to be literally wiped out and instructs a senior civil servant, Mr. Frobisher (Peter Capaldi) to make sure it happens.
