Javier Espada explores how Luis Buñuel, one of the greatest precursors of surrealist cinema through works like An Andalusian Dog and The Golden Age, began to move away from this movement but never completely abandoned it, maintaining a strong oneiric element in his films. Taking us deep into his past and evolution as a creator, this documentary provides an unprecedented window into the world and work of an irreplaceable genius whose influence has reached the rest of the arts.
