After reports of unexplained unruliness at the UN, Danger Mouse and Penfold arrive to scenes of quarrelling diplomats, whose messages of peace and goodwill have been turned into playground insults by the sabotaged translation system. Danger Mouse spots the culprit, Crumhorn, lurking in the shadows and goes after him but is stopped in his tracks by Ian, for whom the UN's security is apparently no match.

If being zapped with a mind-controlling Mindzooka ray by a couple of D-list villains wasn't bad enough, Danger Mouse's shame goes viral thanks to a series of embarrassing videos of our brainwashed hero. Determined to stop the release of the most incriminating video of all, Danger Mouse turns to the villain behind the mind-control tech - the incarcerated Crumhorn! Crumhorn offers an anti-mind control device, but it comes with a catch - he has to be temporarily released back to Crumcorp Towers to retrieve it.
