In 1590, Colorado sent a thousand-man army led by General Fernando de Gama (Miguel Martinez) to enter the legendary golden city of El Dorado to search for gold, but they were attacked by the Skeleton Corps, and none of the thousand survived. Time goes to modern times, Professor Gordon (Miguel Martinez) leads an archaeological team organized by a group of young people to find the site of the Golden City. Under the coercion of three young people driving off-road jeeps, the archaeological team is forced to go with them. After many twists and turns, they finally found the cave where the white bones and gold were buried. This group of uninvited guests awakened the Skeleton Corps guarding the gold, and a war between ancient times and modern times, and between skeletons and humans, began immediately.
