An Arctic station measuring climate change has issues with the ice thinning and hunters going missing in the area, Due to the warming, an isolated evolved species of Greenland Sharks are picking off hunters near the edge. Now you might wonder how an ice station on solid ice could possibly be in any trouble. This is where the fiction part of science fiction comes in.
This is a US TV-14 SyFy Asylum feature that was a warm up for "Sharknado 4", which has spoiled us with "A" lister cameos. The missing leg scene was good and gory, unfortunately it belonged to the only guy (Travis Lincoln Cox) who was believable as a science geek. There was a helicopter in the film, but at no time does a shark leap out of the water, as seen on the DVD cover, and take down the chopper...now that would be silly and is mostly likely saved for any sequel.
