In a world teetering on the brink of divine judgment, where the descendants of Adam and Eve spread across the land, a young woman named Serah finds herself caught in the midst of extraordinary events. Abducted from her village by the enigmatic Nephilim, beings of mysterious origin, she is destined to be presented to their Watcher parents. But fate has other plans for Serah. With courage and cunning, Serah escapes her captors and seeks refuge in the care of Methuselah, an aged sage with knowledge of ancient prophecies. Meanwhile, Shem, a devout and industrious young man, labors alongside his father, Noah, in the monumental task of building an ark-a vessel ordained by the divine to withstand an impending cataclysmic flood. As Shem toils tirelessly to fulfill his part in the grand design, he harbors a secret longing for companionship, fearing he may never find a suitable partner amidst the chaos of their troubled times. Serah, on her own journey of survival and self-discovery, crosses paths with Shem, and amidst the chaos and uncertainty, an unexpected bond forms between them.
