A Dalek mother ship, commanded by a Dalek Supreme, used a tractor beam to abduct a plane carrying an MP who was due to meet the American President, intending to robotise and use him to start World War III, paving the way for a Dalek invasion. However, the Twelfth Doctor was also on the plane, preparing to foil the invasion. (PROSE: Abduction)
