Harbinger Down (2015) 天魔异种

Harbinger Down is a 2015 Russian-American independent science-fiction monster horror film written and directed by Alec Gillis and produced by Tom Woodruff, Jr.; the founders of the special effects company StudioADI.

The plot of the film follows a group of graduate students aboard the eponymous fishing trawler Harbinger who are studying the effects of global warming on a pod of Belugas in the Bering Sea. When the ship's crew discover a block of ice that is infected with alien bacteria, they are attacked by shapeshifting alien monsters.

A group of grad students have booked passage on the crabbing boat Harbinger to study the effects of global warming on a pod of Belugas in the Bering Sea. When the ship's crew dredges up a recently thawed piece of old Soviet space wreckage, things get downright deadly. It seems that the Russians experimented with tardigrades, tiny resilient animals able to withstand the extremes of space radiation. The creatures survived, but not without mutation. Now the crew is exposed to aggressively mutating organisms. And after being locked in ice for 3 decades, the creatures aren't about to give up the warmth of human companionship.
