The Baron uses traffic lights to cause chaos around the world. Everything grinds to a halt. Before DM can tackle the evil fiend the Baron launches a giant traffic light into space and stops the world from turning. Gravity ceases to exist and everyone except for the Baron floats into space. Now he can rule the world... because he's the only one left! It's up to DM and Penfold to get the world spinning again with the help of a hotwired satellite and a Moon-sized image of the Baron's face.

When Danger Mouse and Penfold corner the Baron, the evil villain uses his latest gadget - a tectonic plate spinner - to escape, by rearranging the countries of the world. London is now part of New York and DM is forced to team up with Jeopardy Mouse - his no-nonsense, super-professional American counterpart. When Penfold goes missing DM and Jeopardy must put their differences aside and work together to catch the Baron who is rapidly escaping in Italy. Victory is assured but can anyone remember where all the jumbled countries ought to go?
