Floating above the ice, in a research station deep in the Arctic, a team of expert scientists are studying the effects of climate change on marine life under the thick ice below them. Suddenly, out of nowhere - hell breaks loose when a new breed of aggressive, ravenous sharks suddenly crack through the frozen ocean floor in the middle of the research station, and begin devouring all who fall through. As the ice breaks apart and the station sinks into glacial waters, those alive must band together, and fight off the killer beasts before there are all eaten alive!
