The Missing Crown Jewels

Ant and Dec have lost the Crown Jewels and now the race is on to find them!

 With Head of the Honoured Joanna Lumley on their case, Ant and Dec are introduced to their support team, conveniently made up of some of the biggest MBEs, OBEs and CBEs in showbiz. 
 
Clare Balding, Carol Vorderman, Katherine Jenkins, Alan Shearer, Jessica Ennis, Martin Lewis, Alan Titchmarsh, Gareth Malone, Aled Jones and Dame Shirley Bassey all go by code names that leave Ant and Dec more than a little confused. 
 
But will it take them any closer to the retrieving the Crown Jewels and saving their reputations?
