In an antediluvian world plagued by the corruption of mankind, a man named Noah receives prophetic visions of an impending apocalypse. As a chosen vessel for divine retribution, he is tasked by a higher power to construct an enormous wooden ark to save his family and innocent creatures from a catastrophic flood meant to cleanse the Earth. The visions, filled with both awe and dread, lead Noah to seek guidance from his grandfather Methuselah. With the aid of fallen angels known as the Watchers, Noah embarks on the monumental task of building the ark, arming himself against the skeptical and violent demands of the desperate human race around him.

As Noah and his family labor tirelessly, they grapple with their deep responsibilities and the moral complexities of their mission. Tensions arise within the family as they prepare for the deluge, challenging their beliefs, relationships, and understanding of mercy and justice. The struggle for survival intensifies as they face not only the elemental forces of nature but also the ever-looming threat from men who seek to take the ark for their own salvation. Amidst these trials, Noah is driven by unwavering conviction, bridging the realm between divine duty and human emotion in his quest to fulfill his fateful guardian role.
