Black Wake (2018)

Once a group of scientists gathered in a research laboratory to find out the cause of the mysterious deaths. The main heroine of the Dark Awakening, Dr. Louise Moreira, together with her colleagues are investigating evidence from the scene of the tragedy. On the shores of the Atlantic Ocean, dead bodies are constantly being discovered.
The police declares in one voice that this is the work of a serial maniac. But Louise is sure that a much more terrible creature than a human being is mixed in here. And this ancient evil lurking in the depths of the ocean and waiting for a new victim. The version is absurd, but it also has a place to exist.
