Planet of the Sharks

In the near future, glacial melting has covered 98% of earth's landmass. Sharks have flourished, eating all underwater life.They now dominate the planet, operating as one massive school led by a terrifyingly greedy mutated alpha-shark. The only human survivors live in terror of the predators, and it’s up to them, and them alone, to take down the gigantic cheif shark and make the seas safe again.
