| Summary | In a chilling descent from scholarly ambition to obsession, a once-promising scientist’s life unravels after a fateful encounter at a train station staircase. Tasked with cataloging passengers for a statistical study, he becomes fixated on a mysterious woman’s legs—a haunting image that consumes him, warping his ethical convictions. Years later, now employed at a prestigious research institute, he navigates a labyrinth of secrets among eccentric colleagues: a statistics-obsessed professor, a enigmatic librarian with a hidden past, and a captivating young woman whose presence stirs both desire and dread. When a series of grisly murders rocks the institute—each victim strangled by their own necktie—he is thrust into a web of suspicion, forced to confront his darkest impulses while untangling connections between the killings and his own fractured psyche. Amid spiral staircases that twist like psychological mazes and experiments blurring science and voyeurism, the line between pursuer and perpetrator dissolves, leaving him ensnared in a game where obsession may be the deadliest clue. |
