Godzilla: King of the Monsters follows the heroic efforts of the cryptozoological agency Monarch as its members face off against a battery of god-sized monsters, including the mighty Godzilla, who collides with Mothra, Rodan, and its ultimate nemesis, the three-headed King Ghidorah. When these ancient super-species--thought to be mere myths--rise again, they all vie for supremacy, leaving humanity's very existence hanging in the balance.
