The epic next chapter in the cinematic Monsterverse pits two of the greatest icons in motion picture history against each other--the fearsome Godzilla and the mighty Kong--with humanity caught in the balance.

After the Vietnam war, a team of scientists explores an uncharted island in the Pacific, venturing into the domain of the mighty Kong and must fight to escape a primal Eden.

Japan is plunged into chaos upon the appearance of a giant monster.

When a mechanical replica of King Kong is unable to dig for the highly radioactive Element X at the North Pole, the evil Doctor Who and his sponsor Madame Piranha (Madame X in the American release) decide to kidnap the real Kong. As an insurance policy they kidnap Lt. Susan Miller as well as her boyfriend Lt. CommanderJiro Nomura and Cmdr. Carl Nelson (Kong developed a crush on Susan when she Nomura and Nelson visited the Kong at his home on Mondo Island). Kong later escapes and heads for Tokyo. Susan and the others also escape. Who and his minions follow him and activate Mechani-Kong in order to recapture him. Susan is then grabbed by the robot and is taken to the top of Tokyo Tower and a battle ensues between Kong and his robotic replica.
