Some time after the Mousekewitz's have settled in America, they find that they are still having problems with the threat of cats. That makes them eager to try another home out in the west, where they are promised that mice and cats live in peace. Unfortunately, the one making this claim is an oily con artist named Cat R. Waul who is intent on his own sinister plan.

In Idaho, right-wingers, racists and conservatives are gathering. They reject the state and want to make their own laws. Right-wing militias such as the North Idaho Militia have been active in the region for a long time. Together with the ultraconservatives, they are fighting against a multicultural America and for a new white and Christian colony, separate from the rest of the United States. But the sparsely populated countryside attracts not only radicals, but also more and more middle-class families from the cities. They are excited by the spectacular scenery and the low cost of living. And they want their children to grow up in a supposedly perfect world.
