Le trésor secret de Tarzan (1941)

Mountains of endless virgin gold gleam atop the colossal and steep Mutia Escarpment, and fragments of the rare precious metal dazzle the wide-eyed Boy who, naturally, wants to get a taste of the incredible wonders of civilisation. However, when Boy sneaks off to see the world, a chance encounter with Professor Elliott and his unscrupulous companions, Medford and Vandermeer, will spread a wild gold fever, as those ruthless white prospectors are after the land's untouched deposits. Will Tarzan yield to the evil adventurers' ultimatum?
