The film's script contains only once sentence: “Let a fly walk on a woman's body from toe to head and fly out of the window.” This basically sums up the physical action in the movie. But the basis of “Fly” is the emotional action – that what lies beneath the apathy of the comatose-like lying woman and the insect’s intrusive wish to investigate every centimeter of the naked body. This is a visual parable of feminism ideas with Yoko Ono’s especially exceptional soundtrack.
