ver Cuevana 3. A Good Wolf is a feature-length documentary film examining a 40-year conflict over a single tract of land adjacent to Denali National Park—a volatile struggle between state and federal authorities, fur trappers and wildlife advocates, and competing human interests on public lands. Armed with thorough data, biologists and activists bring a new proposal to state authorities, hoping to regain protections for wolves near the park boundary. But local trappers are adamantly opposed. Hanging in the balance are some of America’s most iconic landscapes and wildlife -- including the remarkable Wolf 1202.
