Tarzan loves Jane, but she has promised to marry another. Heartsick and lonely, Tarzan sails to Paris to learn the ways of civilization from his friend D'Arnot. On board ship--and later in the cafes and streets of Paris--he learns that the jungle is not the only place where savage beasts dwell. Before setting foot on French soil, Tarzan is caught up in a whirlwind of blackmail, attempted murder, kidnapping, and the intrigues of desperate men and beautiful women. When a secret mission takes him back to Africa, he struggles with a decision: Can he stay in the world of the woman he has loved and lost? Or does destiny call him back to his original African home?
