On a foggy winter morning, high school kids Luca and Emma discover the impossible: the wreck of an 18th-century ship stranded in a flower field. Emma enters the hatch on the deck and is never seen again. And she isn’t the last to disappear. Soon a government agency begins to investigate, determined to uncover the ship’s secrets before a media storm erupts. They enlist Robert Grim, a retired specialist of the occult, to unravel the mystery, and he soon realizes the ship could be a harbinger of an ancient doom awakened under the sea. In a maelstrom of international intrigue and pure terror, Grim and Luca must race against time as they come face-to-face with an open doorway to the apocalypse.

Travel journalist and mountaineer Nick Grevers awakes from a coma to find that his climbing buddy, Augustin, is missing and presumed dead. Nick’s own injuries are as extensive as they are horrifying, and he claims amnesia --- but he remembers everything. He remembers how he and Augustin were mysteriously drawn to the Maudit, a remote and scarcely documented peak in the Swiss Alps. He remembers how the slopes of Maudit were eerily quiet, and how they got the ominous sense that they were not alone. But it isn’t just the memory of the accident that haunts Nick. Something has awakened inside of him, something that endangers the lives of everyone around him.
