Leviathan

Synopsis

A catastrophic comet impact melted the global polar ice caps, submerging the world beneath an endless, post-apocalyptic ocean inhabited by carnivorous prehistoric sea beasts. Humanity ekes out a brutal existence on cobbled flotillas and armed ships. Bota and his younger sister survive under the tutelage of their harpooner father until a legendary oceanic leviathan forces Bota onto the front lines of aquatic survival.
