Episode 177
Season 36 – Production code 16DWA177
Written by Rachel Steffan
The hope of an entire world rests on the shoulders of a young child. But there are those who want the boy for their own reasons. When the Doctor involves himself, he finds that he has set in motion a chain of events that will end all life on the planet.
Even the best of intentions are meaningless unless the Doctor can somehow undo the damage he has wrought, and still find a way to end an injustice that has been going on for generations.
