An unassuming dog kennel on top of Buckingham Palace is home to C.O.R.G.I. - by day, simply pets yapping at Her Majesty's heels, but by night, a keen-eyed, wet-nosed pack of highly trained canine agents. The team utilises state-of-the-art speaky bones and high-tech pooper-scoopers to defend the crown. When Prince Cedric, the 29th of the Royal Household of Utter Phalia, discovers his ceremonial pants missing, a major incident has to be averted.

But who can help?.
