By following the battles of five different people, all battling different invasive species in their own local environments, we get to know them, the unwelcome species, and the landscape that they want to protect from uncontrolled evolution. Nature is an open battlefield, and these people know it. They will do whatever it takes to protect the landscape from the intruders. This film is a documentation of different hunts for different invasive species, a study of what it means to be invasive, and a modern perspective on nature in the Anthropocene era.
