In the episode, the alien time traveller the Ninth Doctor (Christopher Eccleston) and his companion Rose Tyler (Billie Piper), having been joined by near-future genius Adam Mitchell (Bruno Langley), land on Satellite 5 in the year 200,000. Satellite 5 is a space station that broadcasts news across the entire human empire. However, the Doctor notices that the station is suspicious: there are no aliens, and those who are promoted to Floor 500 seem to disappear. The Doctor and Rose discover that the Editor (Simon Pegg) and an alien are controlling the rest of humanity by way of the press. Meanwhile, Adam makes a mistake that forces the Doctor and Rose to take him home.
