A little hippopotamus is looking for his most beautiful mother in the world. On his way, he goes to the city, where he visits a film studio and even a zoo. However, only by involving an experienced detective dog will he be able to find her. Elements of a detective story and a musical are introduced into the film's plot, which gives it a parodic tone, but does not diminish the importance and seriousness of the animal protection issue raised in the film.
