While Spirou was thought to have been lost forever, buried under the waters, the groom wakes up in 1958, in the middle of Spirou and the bull-men, after having been knocked out in the salon of Herbert D'Oups. From then on, all the adventures experienced since then are chimeras and the underwater city of Korallion-la-Ville-Bulle never existed. Here it is back in its golden age, the year of the Universal Exhibition of Brussels. We present the future as we imagine it at the time... But the future, Spirou knows that it will not look like this because he, he saw it in dream. Little by little, the doubt settles in him while Fantasio's behavior becomes more and more strange. Welcome to The Memory of the Future, the continuation of the Death of Spirou!
