The film follows a group of students jumping aboard the fishing boat Harbinger to study the effects of global warming on a group of killer whales in the Bering Sea. When the crew pulls up a piece of Russian space debris from the ice, things start to become deadly. It is found that the Russians experimented with tardigrades, small, durable animals having the ability to withstand extreme amounts of space radiation. These creatures survived, but not without mutations. Now the crew is exposed to a mutagenic, aggressive organism.
