Ant & Dec join "The Honoured" - a secret service staffed by celebrities with honours. When the Crown Jewels are stolen on Ant & Dec's watch, their new boss Joanna Lumley tasks the boys with tracking down the mysterious villain known as Maskface before they sit on the throne and become the reigning monarch.

When Simon Cowell is shot at his celebrity-filled birthday party, Ant & Dec are accused of the crime and forced to go on the run, with hilarious consequences. With the authorities hot on their trails, the boys investigate to find the real culprit, in order to clear their name and reveal who really shot Simon Cowell.

Ant & Dec tackle their second mission for "The Honoured" by finding out who is kidnapping its members, including the organisations' leader.
