In the depths of Riotspolis live the Goliath snails that move with ease upon the rocks on which the city is founded. Lindsey, a young, recently qualified mechanic, has become convinced that this ease could be exploited in the Crazy Races organized by the city's completely loony engineers. After several fruitless attempts, Lindsey has transformed the creature into a real racing machine capable of driving round Riotspolis in just a few minutes up against the wall. And that’s without even using the nitro mode!
It was during recent work on the new Clint City subway line that the underground shelter, housing Riotspolis, was drilled apart. This Utopian city, dreamt up by wise men at the turn of the century, could now wave goodbye to its tranquility and isolation. Unsurprisingly upset by this turn of events, the Riotsville Council, led by the Patriarch Pericles, decided that the time had come for them to at last emerge from their isolation and impose their “wise rulings” on this barbaric bunch of hoodlums inhabiting the surface.
