This script takes recent graduate Linlin's thrilling experiences in an old apartment as its main thread, containing profound positive ideological connotations. It exposes Chen Mo's despicable acts of using his authority to entrap and violate single women, and criticizes Lao Zhou's psychological distortion caused by his daughter's death, using paranoid obsession to spy on and interfere with other people's lives. It demonstrates the danger and malice hidden in daily relationships, emphasizing that "evil deeds ultimately receive punishment," and the perpetrator ultimately cannot escape legal sanction and righteous backlash. Linlin goes from the naive timidity of first entering society, facing the fear and helplessness of strange events in the apartment, to gradually observing calmly and facing danger directly.
