Ryann (Ariel Gade) is visiting her grandfather (Christopher Lloyd) in Montana. When a wild wolf-dog shows up injured on the back porch, she wants to take him back to Boston as a pet but her grandfather knows the animal must eventually return to the wild. To help his granddaughter understand, he reads her Jack London's "Call of the Wild" each night. But Ryann has ideas of her own and helps a local boy train the magnificent animal to become a sled dog leader.
