The Idiot's Lantern

The Doctor, intending to take Rose to an Elvis Presley concert in New York City, mislands the TARDIS in Muswell Hill, London on the day before the coronation of Queen Elizabeth II. The Doctor's curiosity is piqued when they see people, their faces covered by sheets, being taken away by police. The Doctor befriends teenaged Tommy Connolly who shows him his grandmother, devoid of any facial features and lacking any brain activity. Tommy admits the problems started when they all started buying inexpensive television sets in preparation for the coronation from Mr Magpie. The Doctor follows where the police are taking the faceless people while Rose investigates Magpie's shop. There, she discovers an entity calling itself the Wire, an alien being that managed to escape execution by its people by turning itself into an electrical form, and now presents its as a spokeswoman on Magpie's television sets, seeking to consume enough minds to recreate its own body and planning on using the wide broadcast of the coronation to do so. Rose is unable to flee before the Wire steals her face as well.As the Doctor is studying the other victims, the faceless Rose is brought in by the police. The Doctor races back to Tommy to enlist his help as they go to Magpie's store and confront its owner. The Wire reveals its plans to the Doctor and tries to consume him and Tommy, but the Doctor fights back with his sonic screwdriver. The Wire retreats into a portable television Mr. Magpie created, and he escapes, intent on reaching the Alexandra Palace transmitter. The Doctor, with Tommy's help, uses equipment from Magpie's shop and his TARDIS to create a device to capture the Wire, and shortly follow Mr. Magpie. As Magpie connects the portable device to the tower, allowing the Wire to start to draw in the viewers' minds while killing Magpie in the process, the Doctor is able to connect his device to the transmitter. The Wire is pulled into the device, and viewers continue to safely watch the coronation; similarly, the minds and faces of those consumed by the Wire are returned to normal. The Doctor shows Tommy that he has captured the Wire on a Betamax cassette, which he will have Rose remind him later to tape over in order to destroy the entity. Rose is reunited with the Doctor, and the two celebrate the coronation with the rest of London.
