Nightwatch

In the heart of Copenhagen, a young law student named Martin Bork takes on a night watchman job at the city's forensic medicine department. As he navigates the dark and eerie hallways, he discovers that his new workplace holds more than just dead bodies. With a serial killer on the loose, Martin becomes embroiled in a dangerous game of cat and mouse, where the lines between innocence and guilt blur. As the body count rises, Martin finds himself at the center of an investigation that threatens to consume him entirely. Is he just a pawn in a twisted game or is he capable of unspeakable horrors? The nightwatch has begun, but who will make it through until dawn?
