The video image shows the interior of an empty, open space: the borderline between inside and out is thin. Human presence can only be felt through the adjoining sounds: a male voice recalls horrendous TV-images, a popular disaster movie, a long-term imprisonment or hostage-taking. The radical rift between sound and image reveals a film which needs to be listened to and brings the described scenes uncomfortably close to the visitors. 'Proof of Life' is a sound movie with empty images which testify to their own, problematic redundancy.
