In a city that has been devastated by a strange epidemic, chaos and terror unfold after a group of rescuers ventures into an abandoned building, filled with shadows and secrets. Survivors of a mysterious infection that transforms people into demonic creatures are being rescued and taken to a military ship offshore for evacuation. Among them is Angela, the journalist who started it all in the first episode of this nightmare, who is brought aboard, but her dark past and memories of what she has lived through soon begin to torment her.
As the crew and some rescuers attempt to maintain calm, tension mounts. However, the threat has not disappeared. Something on the ship begins to infect the crew members one by one, forcing them to fight not only for their survival but also for their sanity. The dark secrets of the laboratory investigating the outbreak are revealed, shedding light on the origin of the infection and unleashing uncontrollable terror. As the situation becomes unsustainable, the search for answers turns into a struggle to stay alive.
The claustrophobia of the ship and the constant lurking of the threat, whether from the depths of the ocean or from the shadows of the ship itself, keep adrenaline levels high. The fight is not only against the supernatural but also against oneself in this intense chapter of the apocalypse.
