Planet of the Sharks

In the near future, glacial melting has covered 98% of earth's landmass. Sharks have flourished and now dominate the planet, operating as one massive school led by a mutated alpha shark.

On a future earth where 98% of the surface is underwater, a Warlord who controls an army of sharks meets his match when he captures the daughter of a mysterious shark caller who must learn to marshal a supernatural ability if she is to free her people from the Warlord's dominion.
