'What I do is very simple. I take photographs of people. For my work, I mainly take photographs of people in compromising situations. I don't hire models. I use real people, in real situations, secretly. I steal their images. And I use myself.' Petra is more than just a voyeur: she finds her sexual gratification from her intrusion into the secret life of others. Living in a high-rise apartment, she spies on opposite windows and constructs photographic sex fantasies from the scenes she witnesses. Petra becomes obsessed with a sexually adventurous couple and is soon caught up in a spiral of desire and sensual excess. How far will it go?
