After setting foot on the isolated territory of the Cobra tribe, Tarzan, the magnificent lord of all wild animals, and a scientific expedition find themselves in grave danger.

In search of the elusive Cobra tribe, Professor Dayal ventures into the impenetrable, peril-laden jungle along with his daughter, Leena, and his right-hand man, Johnny. As the expedition enters the green realm of Tarzan, the magnificent lord of all wild animals, a pair of stealthy, money-obsessed opportunists searching for the tribe's fabled treasure is hot on their trail. Before long, Tarzan and Dayal's team catch the attention of the fierce Cobras, whose evil high priest wants to offer them as a blood sacrifice to the sacred God of Fire. But the seductive Princess Samara has already taken a shine to mighty Tarzan, and she wants him all to herself. Can Tarzan escape captivity and save beautiful Leena, and the others, from certain death?—Nick Riganas
