Jason, Tann, and Lua are attending an exclusive auction of relics in NY City. Tann outbids the evil Professor Ramone De La Porta for an ancient Atlantean stone tablet, paying ten million dollars! Afterwards Ramone's henchmen attack them, one of whom transforms into a horrible Cyber-link monster, the Omar/dog. Jason merges with Kong to beat back the creature, but in the battle the stone tablet is broken. De La Porta takes the biggest piece and races off to India with our heroes hot in pursuit. They catch up with him in the legendary lost Palace of the Maharajah high in the mountains. Using the stone tablet and the Primal Stone of Fire, the Professor opens a Portal allowing the titanic Fire Cobra to enter our world. Without the full tablet De La Porta cannot control the monstrous creature and the out of control Cobra threatens to burn the world to ashes! Kong valiantly battles the monster allowing our heroes to destroy the Stone of Fire Portal and causing the Fire Cobra to vanish.

Our heroes track De La Porta to the jungles of Burma and the fantastic Forgotten City. In a ruined temple, the Professor tries to activate the Primal Stone of Time. Jason, Tann, and Lua attempt to stop him but are transformed into children by the powers of the Primal Stone. They take the Stone and escape with Kong. The giant ape has his hands full dealing with the younger versions of his friends. De La Porta's henchmen attack, led by a horrible Cyber-link created monstrosity--Giggles/tarantula. Kong defeats the creature in a wild fight, but the children are recaptured along with the Stone. Kong attacks De La Porta and in the ensuing chaos, the Professor and his men are also turned into children. With some clever detective work, Jason and his friends figure out how to reverse the Stone's power and return everyone to their normal ages.
