The film "Where Do Frogs Come From?" observes the reproduction process of the two most common frog species in Northern Europe - the common frog and the common toad - from spring migration to the tadpole-to-frog transformation in high summer. Frog action takes place on land as well as on and under water. Things for the froggies do not always go without a hitch and they too struggle with miscalculations. There are misunderstandings and quarrels they endeavor to resolve. The life of tadpoles falls short of a carefree childhood and the little guys must resort to a variety of tricks to survive.
