At the height of his powers of image manipulation, Jean Lecointre takes his hero on an introspective-phantasmagorical voyage to Barcarolle, the island of all possibilities. Will he rediscover the desire to live? Poulenc, a "star" researcher in his field, explores the human psyche. Thanks to drugs, he reaches levels of consciousness never imagined. But the euphoria of success has become a nightmare. Dependent, uncontrollable, and in the throes of an existential crisis, the hero seeks a way out.
