It was just supposed to be another little glimpse into the future, that's what the Doctor and Rose had planned. What they weren't expecting was to land on an almost barren Earth after what seemed like another alien invasion.

With their freedom slowly slipping through their fingers, the last of the free people feel like they're being forced to go with the invaders... Until now.
