The novel's central character is a dog named Buck, a domesticated dog living at a ranch in California as the story opens. Stolen from his home and sold into the brutal existence of an Alaskan sled dog, he reverts to atavistic traits. Buck is forced to adjust to, and survive, cruel treatments and fight to dominate other dogs in a harsh climate. Eventually he sheds the veneer of civilization, relying on primordial instincts and lessons he learns, to emerge as a leader in the wild.
