In the film Contra Natura (Unnatural), climate change is affecting all regions of the planet, even the coldest. These regions include Alaska, which is the cradle of polar bears, a species that is also suffering from climate change, as there is less and less ice.
One company, we do not know what the reason is, decides that it is time to genetically modify the bears, perhaps with the intention of adapting better to the new climate. Be that as it may, the truth is that the company does and creates bears with a new genetics.
What the company does not know is that its genetic manipulation causes the bears to become even more aggressive, which is a lot to say when we talk about one of the most aggressive species on the planet.
Now, the inhabitants of the area have a very serious problem, because the bears are always lurking in order to attack everything that is alive, whether human or not.
