'The schoolboy whose twin brother vanished in the night. A woman whose house teems with alien refugees. The dad who dies every evening...
All through space and time live people, ordinary people, whose lives have been turned upside down.
People who've lost jobs and loved ones, or seen their homes destroyed, or found themselves on whole other planets. They've nothing in common with one another except that their lives can never be the same. Because they're people who've met the Doctor.'
