Based on the play 'Magic' by G.K Chesterton. A conjurer, feeling cornered by a hostile audience, turns an evening of simple parlor magic into a night of madness by performing one last trick. How does he do it? That is the grand question.
In emblematic places around the world, Frédéric Lenoir, philosopher, sociologist and writer, goes to meet those who experience a spiritual quest, both religious and secular. A pilgrimage that mixes the voices of anonymous witnesses and personalities such as the Buddhist monk Matthieu Ricard, the apneist Guillaume Néry and the astrophysicist Hubert Reeves.
