Noah is a biblical epic that tells the story of a man named Noah (played by Russell Crowe) who begins to have prophetic visions of a great flood that will destroy all life on Earth. Convinced that this is a divine warning, Noah becomes obsessed with building an ark to save his family and the animal kingdom from the impending deluge.
Noah is aided in his mission by his wife Naameh (played by Jennifer Connelly) and their three sons, Shem, Ham, and Japheth. Along the way, they encounter the fallen angels known as the Watchers, who have been banished to Earth and are cursed to live as stone giants. The Watchers help Noah build the ark and defend it against the wrath of the wicked men who seek to steal it and survive the flood.
Meanwhile, Noah is haunted by his own demons and struggles to come to terms with the harsh reality of God's plan. He questions whether humanity deserves to be saved and grapples with the morality of taking life on such a grand scale.
As the flood draws nearer and the ark nears completion, tensions rise among the group and Noah's resolve is tested. The film ultimately culminates in a breathtaking depiction of the flood and its aftermath, as Noah and his family attempt to make a new life in a world that has been irrevocably changed.
