Tarzan's Greatest Adventure

Led by vicious Slade, his gang of thieves -- O'Bannion, Dino, Kruger, and Slade's Italian girlfriend, Toni -- raid defenceless villages along the serpentine river within mighty Tarzan's territory. As they work their way upriver, plundering weapons, supplies, and explosives, two men die, and Tarzan, along with downed pilot Angie Loring, embarks on a mission to stop them before they reach a hidden diamond mine that's exact location only Slade knows. Without a doubt, greed, and the fever of gold, can turn a person mad and, even though the unforgiving jungle is rife with formidable adversaries, Slade and his jackals are bent on finding the mine at all costs. Can Tarzan's arrows stop the gun-toting invaders?
