A documentary on Raymond Roussel, who inspired the surrealist group, Marcel Proust and countless novelists and artists of today, from Enrique Vila-Matas and Miquel Barceló to Jan Svankmajer. Taking as our point of departure the film ''Impressions de la Haute Mongolie'' (1976), which Salvador Dalí and his director José Montes-Baquer dedicated to Roussel, different specialists including Michel Butor uncover the figure of this writer and poet on a journey through literature, music and the visual arts, taking us from Barcelona to Mallorca, Madrid, Germany, France, Italy, Austria and the US. And from the microscopic ink-impregnated images to the most singular portrait of the human soul. With John Ashbery, Michel Butor, Jan Svankmajer, Harry Mathews, Jean-Jacques Pauvert, Enrique Vila-Matas, Annie Le Brun, Hermes Salceda, Miquel Barceló, Lillian Schwartz, Mark Pauline, Alfred Maas, Fred Barzyk, Bill Etra, Manfred Kage, Bodo Kessler, Barbara London, Jean-Christophe Averty, Robert Descharnes, Nicolas Descharnes and Vittoria Alliata.
