"Beauty will be convulsive...." It's 1941. In the chaos of wartime Marseille, American engineer - and occult disciple - Jack Parsons stumbles onto a clandestine anti-Nazi group, including surrealist theorist André Breton. In the strange games of the dissident diplomats, exiled revolutionaries, and avant-garde artists, Parsons finds and channels hope. But what he unwittingly unleashes is the power of dreams and nightmares, changing the war and the world forever. It's 1950. A lone surrealist fighter, Thibaut, walks a new, hallucinogenic Paris, where Nazis and the Resistance are trapped in unending conflict, and the streets are stalked by living images and texts - and by the forces of hell. To escape the city, he must join forces with Sam, an American photographer intent on recording the ruins, and make common cause with a powerful, enigmatic figure of chance and rebellion: the exquisite corpse. But Sam is being hunted. And new secrets will emerge that will test all their loyalties - to each other, to Paris old and new, and to reality itself.
