Taking refuge from a world-ending flood on an Ark constructed to save the animals, Dave and Hazel struggle to save their respective children, Finny and Leah, after they tumble from the Ark and into the dangerous waters outside.
With the coming of the divine flood, Noah's arch is built and ready to shelter those animals who will be spared the deluge. To their dismay, Dave and Finny find out they are not among the chosen ones, so they sneak into the arch, without anyone noticing. They make it, but Finny falls overboard and tries to survive through the rising waters, along with Leah. Adventure ensues.
