Emily Fletcher is the new girl in Stonehill, Pennsylvania. When a wild cat is brought in to her mom's animal hospital with strange burns, Emily finds that this animal can communicate with her. She then discovers that Adriane, who lives on the local wildlife preserve, can also speak with strange animals. These animals seem to think that the girls can help, but how? With the help of a talking ferret (who claims he is a dwarf) and the snobby mayor's daughter, the girls realize that there is a whole other world... and it's in trouble!
