Gotron and his Raider Apes attack a nearby village, intent on stealing the people's gold. Summoned by the villagers, the Herculoids arrive nd follow the apes into the cave the gold is hidden in. The villains eventually recover their gold, and load it onto their ship. However, the ship is so weighted down with gold that it can barely move. Zandor sends Zok out with one last bag of loot. The dragon drops it right on Gotron's face, and the ship sinks. The chief of the village reveals that the survivors got away and Zandor suspects that Gotron will one day return.
