故事讲述珍妮佛努力走出创伤的同时，却发现自己回到了一个完全陌生且危机四伏的世界。

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.)

《瀑布》的故事灵感来自导演钟孟宏友人发生的真实故事，以电影《瀑布》中层层暗喻与不停撞击两个女主角的故事为设计概念主轴，就有如海报中的草丛，缓缓持续着围绕这着母女，像是保护他们又像是被团团困住。而她们背后的蓝色帏幕象征未完工且令人期待的未来，蓝色的基底又像是层层水幕，大量的水花如瀑布般向下坠落。
