Eight-year-old Lily can suddenly hear every animal. Her dad's zoo is dying, and her mom gave one last month: if it doesn't turn a profit, she's leaving for good. No trainer can calm the beasts, but Lily can. She rides a hippo to brush its teeth, turns a raging cougar into the zoo's sweeper, and teaches a lonely elephant to dance. Each wounded animal becomes her friend, and the zoo slowly comes back to life. Lily's only wish is simple: save the zoo, and bring her mom home.
