Black Jack is called out to the jungles of Indonesia to help an old friend with some unique research. Renowned Paris based Professor Dr. Triufeaux has stumbled upon a rare case of a modern day wolf-boy. Raised by a flat-headed cat, the child is extremely afraid of humans but is equally at risk of attack by the jungle's many predators. Black Jack and Triufeaux work together using medicine and educational science to train and nurture the boy back into the world of humans. But you can't take the wild out of a wildcat, and Black Jack will learn just how powerful the big cats of Southeast Asia can be.
