Colonel K's comments while opening the Danger Museum rile his old nemesis into breaking out of Arkwright Asylum. Brigadier Burt Badboy robs the museum and gets hold of his old weapons. He'll make the Colonel pay for his rude comments! The Colonel tries to deal with the villain personally but only makes the problem worse and has a crisis of confidence as the Brigadier uses his rudeboy bullhorn to spread anti-social behaviour. With DM and Penfold paralysed by rudeness the Colonel knows the world needs him to dust off his old battle blazer and take on his ancient nemesis one last time.

When secret information is leaked from HQ all eyes fall on Colonel K! Is it possible he's a traitor or is there something suspicious about his moustache?
