Sebastian, a man haunted by a tragic past and struggling to rebuild his life after losing his daughter and his job, takes a one-week position as a janitor at a university campus. What seems like a simple, quiet gig quickly turns into a nightmare. His responsibility: keeping an eye on five students-Oliver, Jayden, Rebecca, Emma, and Sofia-who are all suspected of being connected to the mysterious death of Professor Vicario just a week earlier. As Sebastian works to maintain order among the group, he uncovers a chilling connection: the professor's death may be tied to an old ghost story that has haunted the campus for years.
