Molly and Terrance are two civilized mice trying to quietly live in Mouseland while abiding by the laws created by Mice International. One morning while on food procurement duty in a suburban kitchen, Molly and Terrance barely escape with their lives before being detected by the Jones family-but not before they overhear Mrs. Jones threatening to fumigate the house! Thankfully not everyone in the Jones house hates mice. The children, Samantha and Cianan, love the little creatures and will do anything to protect them. Meanwhile, all the mice of Mouseland have other challenges that include a trio of rat bullies-Shake, Rattelle, and Roll-and a neighbor lady who also hates mice. When Mrs. Jones decides to have her home fumigated, she plans a family camping trip. After her children forewarn the mice, the tiny creatures decide they should go camping too. But there's only one problem: the rat trio is up to no good. Now it is up to a homeless dog to save them all, before it is too late. In this delightful tale, a homeless dog and a group of mice teach a suburban family and other animals how to be kind and live in harmony.
