The Ninth Doctor, Rose, and Adam arrive on Satellite 5, a space station orbiting Earth in the year 200,000. The Doctor gets Adam and Rose some credits to buy food while he looks around the station. The Doctor meets a woman named Cathica, a reporter who tells him that the station is a giant broadcast tower transmitting news across Earth. Cathica leads them to a room where she sits down in a chair located in the centre of a round table. The reporters are connected to the computer via a special port installed directly into the brain. The Doctor believes there is a malevolent purpose to the station that is holding back human development. He learns from Cathica that a select few are invited to Floor 500, which is believed to be the highest promotion that can be earned on the station.
