A young dog, Buck, grew up as the favourite pet of a loving family, in California. But his life took a sudden turn when he was sold by a rogue servant and was transported to the far North. The Cold, wild land was cruel and heartless; inhabited by greedy gold prospectors, savage wolves and even more savage Indians. Buck became a sled dog and was subjected to a life of immense hardship. He soon realised that he must return to the law of the wild and learn to survive. Buck turned to the ways of his forefathers using the cunning, toughness and ferocity that lay dormant in him - he became the strongest sled dog in Alaska. But can he overcome the urge to run free of man's rule; the urge to respond to the call of the wild?.
