 In a surrealistic and bizarre society, children have been abducted by a mad and evil scientist, Krank (D. Emilfork), who wants to steal their dreams and stop and reverse his accelerated aging process. When the gang of Cyclops kidnap Denree (Joseph Lucien), the little brother of the former whale hunter One (Ron Perlman), he is helped by the young street orphan girl Miette (Judith Vittet), who steals for the Siamese Pieuvre (Geneviève Brunet & Odille Mallet), to reach the platform where Krank leaves with his cloned dwarf wife Mademoiselle Bismuth (Mireille Moissé), his six cloned sons (Dominique Pinon) and a brain, and rescue the children.
