Ono’s work related destruction to interpersonal, often intimate, human relations. This element was particularly thought-provoking in ?Cut Piece?, one of many actions she did as DIAS [Destruction in Art Symposium]. Ono had first done the performance in 1964, in Japan, and again at Carnegie Hall, in New York, in 1965. Ono sat motionless on the stage after inviting the audience to come up and cut away her clothing, covering her breasts at the moemnt of unbosoming. ?Cut Piece? entailed a disrobing, a denouement of the reciprocity between exhibitionism and scopic desires, between victim and assailant, between sadist and masochist: and, as a heterosexual herselft, Ono unveiled the gendered relationship of male and female subjects as objects for each other.(source: Kristine Stiles,?Uncorrupted Joy: International Art Actions,? in: Out of Actions: between performance and the object, 1949–1979, Paul Schimmel (ed.), MoCA Los Angeles, New York/London, 1998, p. 278.)

电影故事原型来自真实传闻已久、发生在台中东海大学“女鬼桥”的校园灵异事件：相传有一位女学生被负心男抛弃，午夜时从桥上跳河自尽，自此那座桥就发生多次灵异现象，故被学生命名为“女鬼桥”。2018年时有一位学生凌晨独自到女鬼桥直播，期间有网友突然发现直播背景的树上疑似有一名身穿白衣女子飘在空中。当时这件“撞鬼直播”事件引爆网路讨论，《女鬼桥》的故事就由此延伸，更配合一连串以观众为第一视角、不间断的惊悚恐怖场面，务求令观众一路惊到尾，直奔最后惊人结局！
