Wandering in a London park, Thomas, a fashion photographer, takes photos of lovers embracing. Jane, the woman, runs after him demanding he give her the exposed film. He refuses. She tracks him to his studio, removes her shirt, and to get the film she attempts to seduce him. Thomas gives her the wrong roll. After Jane leaves Thomas blows up the roll. Shockingly, one of the photos showed what looked like a murder taking place. Thomas begins to make prints of each photo as he begins to notice a gunman in the bushes and a man, presumably dead, lying on the ground. Thomas surmises that Jane was having an adulterous affair. Feverishly, Thomas continues to look at the prints trying to understand what really happened in the park.
