In recent years, the murder of women in society has been common, sounding the alarm bell of women's self-protection again and again. The movie "Door Lock" hopes to explore the problem of how women living alone should protect themselves by exposing the potential dangers of women in life and work. The film directly attacks the topic of hidden pain in society, mobilizes the public's emotional resonance and rational thinking, promotes society to continue to strengthen its attention to women's safety, and lights a lamp for women to break the shackles and get out of the darkness.

The movie "Door Lock" is produced by the leader of the domestic crime genre film Wubai, directed by the cutting-edge director Buick, starring Bai Baihe, Bai Ke and Fan Chengcheng, and starring Wang Zixuan, Ma Yuke, Liu Huan and Liu Wei. The film takes the problem of contemporary women living alone as the starting point, telling the story of Fang Hui (Bai Baihe), a single professional woman who is confident and beautiful on the surface, finds traces of stranger intrusion in her solitary life and experiences various unsettling encounters. As the first crime film in China to focus on the safety of women living alone, the care and discussion of women's safety and urban white-collar living space in "Door Lock" not only makes up for the gap in the market, but also a unique analysis of hot social issues, which is bound to set off a huge wave of hot discussion after the release.
