High tension in northern Germany: A fire devil is on the loose in Sylt, pursuing a sinister plan. Fires are raging on Sylt. The dining room of a luxury hotel, the waiting area of a bus stop, and the roof of a car are all ablaze. While detectives Sven Winterberg, Silja Blanck, and Bastian Kreuzer feverishly search for the arsonist, journalist Fred Hübner reunites with his former great love, Susanne. She owned the burned hotel, which is why she has returned to the island after years away. But soon, Fred becomes the reason for her stay. As Susanne contemplates leaving her wealthy husband, a murder occurs. And that is just the beginning. The second case for the Sylt investigators Sven Winterberg, Silja Blanck, and Bastian Kreuzer.
