Tiro Mandawa accidentally discovers a mysterious ancient artifact while he is guiding an archaeological mission. The artifact is believed to be the last piece of an ancient inscription related to Indonesian folklore. Prof. Kuncoro, a professor of history on ancient civilization, believes that the artifact is the key to the location of an ancient relic that has an endless powerful force. A giant company, the Madewa Group, headed by Adinoto Madewa is willing to finance the expedition to find the ancient relic. Tiro, and his faithful assistant, Satrio, the head of Madewa Group special staff, Miranda, plus Prof. Kuncoro and his two children, Sandhika and Panji, join this expedition mission. Their work is then obstructed by a treasure hunter, Maulana, who is also after the ancient relic.
