Planet of the Sharks

In the near future, global warming has taken its toll and glacial melting has meant water covers the majority of the earth's landmass. As the sea rises, terrorising sharks have flourished, dominating the planet and operating as one massive school, led by a terrifyingly mutated alpha-shark. After the sharks consume all underwater life, the only food left is the few human survivors, who live in terror of the predators. Now it's up to one small group of people, and them alone, to take down the gigantic chief shark and protect the human race from extinction. (Kaleidoscope Home Entertainment)
