A man writes- what?- his life story or the storyline of a movie. He has trouble and entrusts the task to his double, Lucifer. Together, they review his life. The memories flock. Flashbacks to childhood, excerpts from his old movies and... life goes on. Between refrains, beautiful and daring escapes, the film ends up being written and done before our eyes. A palimpsest film, sampled, enchanting. A history of cinema by itself. The myth of Faust revisited. A long poem, a little paper boat on a river of ink.
