From the Deep e-bog

When nuclear war blackened the sky and scorched the earth, humanity fled the surface to the depths of the world's oceans. Almost a century later, entire civilizations exist thousands of feet down in specially made self-contained environments, carrying on in hopes of one day returning home. At one of these places, in the middle of nowhere, a mysterious and deadly incident occurs, threatening the lives of the more than four hundred people within. With no choice but to survive any way they can, tensions rise as the situation worsens and trust in one another degrades, pushing these people to the absolute limit. Trapped at the bottom of the ocean, there's nowhere to run from the terrors that come from the deep.
