Marty Stouffer is studying wildlife in a remote Colorado wilderness. One spring day, he comes across the tracks of a Grizzly Bear -- thought to be extinct in the state -- and he follows and meets face-to-face with a magnificent male Grizzly. Excited by his discovery, Marty adopts a female Grizzly cub from a zoo. He and Griz share a cabin as Marty teaches her how to survive.
