The Arctic Regions are a permanent reminder of one of the most dramatic periods in the earth’s history, the Ice Age. Some scientists claim the earth is cooling down and another ice age is on the way others say the earth is still warming up and if the trend continues the vast ice caps will begin to melt. Either way, the Polar Regions are under constant and careful scrutiny.

When Sailors on a mission find that the ice caps are melting, a pilot is sent to investigate but when he disappears a team are sent to find out why.

Is is extraterrestrial?
