During one long winter s night in a neon-lit Paris, a restless young man wanders around to let himself be found by something that most people otherwise try to avoid: ghosts. And the night is full of unexpected encounters in this ultra-chic film, which is neither documentary nor fiction, but rather an adaptation of the idea that Jacques Derrida defines in a guest star appearance on the cinema screen: that film plus psychoanalysis is equal to the science of ghosts - ie. a form of spectrography , which the French artist SMITH in her self-ironic, self-conscious, science-fiction essay of a film, conjures up with thermal infrared and in the dialogue s mosaic of quotes of rambling French philosophy, from Breton and Barthes to Merleau-Ponty and Derrida himself. Hyper-modern and rich in (retro) references.
