The Doctor and Chris make their way through several regions of 21st century London. They are following a girl and a hooded figure, thought the Doctor hasn't explained why. They are unaware that they themselves are being followed. They reach Battersea Power Station, which is the office of the president of London. Inside, a contest is under way. The President is holding a contest for the best android, the winner of which he will take into his household staff. The Doctor explains to Chris that the president is "in the pocket" of Perseus, and that their entry is favoured to win.
