Eight-year-old Molly can communicate with animals, but she hasn't spoken since her parents were killed in an accident, forcing her to live with bossy Aunt Wilma. Her classmates bully her, chanting, "Cat's got your tongue!" Molly recruits Tony, a wise black Lab and Rusty, a rambunctious cocker spaniel, to help her track down the tongue-stealing Cat. She gets her tongue back in a surprising way and just in time to save her town from catastrophe.
