When Poseidon grows tired of humanity’s relentless pollution of the oceans, he empowers water with memory, allowing it to remember every harm inflicted upon it and fight back. But his attempt to teach humans a lesson spirals out of control, as water reclaims half of Earth’s habitable land. Furious with his reckless actions, Zeus banishes Poseidon from Olympus and forces him to work with Hades to undo the chaos and restore the planet.
