Behind the scenes of a rewilding project takes us to Mozambique, to the Zinave National Park. Shaken by years of civil war, this park has seen its wildlife decline. In a territory that is now peaceful, a team undertakes to reintroduce a variety of animal species and rebalance the ecosystems. The film illustrates the complexity of the project: which species to reintroduce? In what order? Where to find them and how to make them travel? Will these animals adapt to their new environment? By focusing mainly on herbivorous species, the film explains their complementary role within the ecosystems.
