Family adventure loosely based on the novel by Jack London. Christopher Lloyd stars as Bill Hale, a recently widowed man living in Montana who has his nine-year-old granddaughter Ryann (Ariel Gade) to stay for several weeks while her parents go abroad. When Ryann finds a wounded wild dog on the back porch one night, she names him 'Buck' and dreams of taking him back to the city as a pet. But her grandfather knows that the animal will eventually have to return to the wild, and to help her understand this he starts reading Jack London's 'Call of the Wild' aloud to her each night. However, Ryann has hatched a plan of her own, and enlists the help of a local boy to train Buck up as a sled dog champion.
