Watch City face Wolves on Prime

Yellowstone National Park was once home to an abundance of wild wolves--but park rangers killed the last of their kind in the 1920s. Decades later, the rangers brought them back, with the first wolves arriving from Canada in 1995. This is the incredible true story of one of those wolves. Wolf 8 struggles at first--he is smaller than the other pups, and often bullied--but soon he bonds with an alpha female whose mate was shot.
