Wolves have become a prime object for behavioural research throughout Europe. This is the story of three extraordinary migrators. Slavko covers a distance of more than 1,000 kilometres, from Slovenia across the Austrian Alps well into Northern Italy. Alan sets out from Eastern Germany and finally reaches the border of Belarus. Ligabue migrates from Parma in Northern Italy to the French Alps. What urges single specimens of the European wolf to undertake such highly dangerous journeys?
