A bunch of grad college students have booked passage on the fishing trawler Harbinger to check the results of world warming on a pod of Orcas within the Bering Sea. When the ship's crew dredges up a just lately thawed piece of outdated Soviet area wreckage, issues get downright lethal. It appears that evidently the Russians experimented with tardigrades, tiny resilient animals capable of stand up to the extremes of area radiation. The creatures survived, however not with out mutation. Now the crew is uncovered to aggressively mutating organisms. And after being locked in ice for 3 many years, the creatures aren't about to surrender the heat of human companionship.
