1965

At some point in 1965 the British government was contacted by an alien race dubbed the 456. They demanded a dozen children in exchange for an anti-virus to an influenza outbreak that would otherwise killed millions. Jack Harkness of the Torchwood Institute was ordered to deliver a busload of children from an orphanage in Scotland. One child, Clem McDonald, escaped and ended up on the run, destined to spend the next forty-five years in asylums. With the children delivered, the anti-virus was provided and the flu outbreak was quelled. (TW: Children of Earth: Day One, Children of Earth: Day Four)
