During archaeological excavations in Peru, an ancient mummy is found—belonging to a Spanish Dominican monk. When the mummy is studied using the newest devices, it turns out that in the skull there is strange liquid gold.
On the territory of the excavation site, a subterranean treasure chamber is discovered, which turns out to be a gigantic trap that kills anyone who tries to get inside. Archaeologist Henry Conklin and his assistants attempt to uncover the secrets of an ancient civilization hidden by priests many centuries ago.
