Is Schattenseite coming back?

Cyberbullying and hacker attacks change the lives of the main characters shortly before their high school graduation. Corvin, Nola, Patricia, and Simon are actually looking forward to their future beyond school, but then the "shadow side" appears and changes everything. The website reveals the teenagers' most intimate secrets, and the more people click on it, the more explosive material comes to light. Nothing remains taboo: chat histories, screenshots, nude photos, and videos are suddenly accessible to the public. There's only one chance to stop the leaks: the person affected must cooperate with the "shadow side" – and simultaneously betray their closest friends. Does this all have something to do with the recent death of classmate Linus?
