Professor Luca Rossi is nearing retirement and is followed in his last two years by an ex-doctoral student who made a stunning debut film with Lupi nostri. Different stories explore different aspects of the emotionally charged wolf debate. There is Daniel, Professor Rossi's new PhD student, who uses cameras to follow the wolves to solve the mystery of a dead wolf, ranger Jerry who uses a ‘spy wolf’ to track down the elusive creatures, Mauro who leads an anti-poison unit and Francesca who works with Professor Rossi on the challenging task of capturing and sterilising hybrid wolves. Amidst all this, Rossi's friend Aurelio leads hunters through the wilderness while keeping a close eye on the wolves and sheepherder Giorgio tries to protect his animals.
