Animal rescuers and puppy

It's them again – the animal rescuers: Grandpa Eagle, lanky Matyáš, clever Miki, quiet Petr, slow Erik and his speedy sister Sofie. They are all united by their love for animals and their desire to help.
Grandpa Eagle takes the children on a spring walk to the stream. But along the way, everything goes wrong, Erik ends up in the mud and Grandpa Eagle loses his beloved pocket knife. The rescuers therefore split up to solve all the problems. Along the way, they discover an abandoned puppy that isn't breathing. The fight to save its life is just beginning. Will they succeed? You'll just have to see!
