12-year-old Marina runs away from home: she wants to find a way to cure her dog Taiya, her only true friend, who has not eaten or drunk for two weeks. Marina finds Dr. Gaf, an unsociable veterinarian with an unusual gift: he knows how to communicate with animals. Gaf manages to cure Taya, but at night she is abducted along with other dogs from Dr. Gaf's shelter. Behind this is a company that needs stray animals for illegal experiments on them. Gaf and Marina go in search of their shaggy friends. A variety of animals will help them in this, from pigeons and rats to boa constrictors and skunks.
