In the mountainous highlands, we encounter two endangered predators, both relying on a plentiful supply of lemmings. Luckily, this year there is a surge in the lemming population and so the Arctic Fox and the Snow Owl breed successfully and we get to watch their rearing of the young in intimate detail. The reindeer wandering the plains in a spectacular eternal migration encounter their own challenges breeding. Foxes, ravens and eagles are on a constant lookout for vulnerable calves and the cow even eats her placenta after giving birth so as not to attract the attention of predators.
