Ice Sharks (2016)

Deep in the inhospitable Arctic Circle, at the remote Oasis polar base, a brutal attack by a powerful but unexpected predator terrorises the scientists of the floating research station that is now rapidly sinking in the freezing waters. As the temperature rises due to global warming, and the ice sheet becomes thinner, the prehistoric and hungry-for-human-flesh sharks of the Arctic Ocean find their way into the surface, feeding off the unprotected humans. Now, trapped inside the damaged facility, and with a limited supply of air, the survivors will have to make do with what they've got to stay alive. But can they outsmart the ferocious ice sharks?
