Things begin to happen when there's a smart mouse in the house! Arvee, a clever and scholarly mouse, is horrified to find that he must leave his laboratory to live as a house pet. His new home, Paradise Villa, is charming and comfortable but boring and lonely. All that changes when Arvee meets bright, feisty Ellie and the rest of her family of house mice. They tell him about Pasha, a huge, fearsome rat who, along with his thugs, has taken over Paradise Villa, harassing and enslaving the mice. A small, brave band of rebels is ready to fight back but how? Arvee brings his thinking skills to the struggle, pulling in the help of other house creatures. But Pasha has very different plans for him and Alphonso the cat is not too far behind either. Will Arvee succeed in helping Ellie, her family and all the other mice under attack?
